基于交通模拟的悬浮隧道可靠度分析

Using traffic simulations for structural reliability of a Submerged Floating Tunnel

报告精华（Report Summary）

SFT结构尚未建造。其中一个主要原因是对SFT的结构可靠性认识不足。为了评估可靠性，结构在交通荷载作用下的结构响应是一个模型。该模型将基于连接函数的交通模型和基于基本直接刚度模型的结构响应耦合起来。该方法为获得SFT的真实响应提供了一种创新方法。通过概率分析，可以调整横截面的设计，使其满足弯矩引起的泄漏要求。这种方法可以推广到SFT的其他失效模式或其他结构。

SFT structures has not been constructed yet. One of the main reasons is that there is an insufficient insight into the structural reliability of the SFT. In order to assess the reliability, the structural response of the structure loaded by traffic a model. In this model both the traffic model based on copulas and structural response based on the elementary direct stiffness model are coupled. The method presents an innovative way a possibility to obtain a realistic response of the SFT. Using a probabilistic analysis, the design of the cross-section can be adapted so that it meets the requirements for leakage caused by bending moments. This methodology could be extended to other failure modes of an SFT or to other structures.

水中悬浮隧道设计理论研究进展与实践探索

Theoretical research progress and practical exploration of submerged floating tunnel design in ocean environment

报告精华（Report Summary）

综述了近年来国内外在悬浮隧道断面结构型式、结构动力响应、锚索涡激振动、行车安全、试验技术及防灾减灾等方面的研究进展，总结了研究存在的关键问题及展望。结果表明：结构选型需综合考虑结构断面型式、浮重比与锚索布置方式，以保证其稳定性;整体动力响应与锚索振动特性研究以数值仿真和理论解析为主，需发展物理模型试验技术；有必要建设小型悬浮隧道对静态水域开展实体隧道研究，为复杂海况下大型悬浮隧道建设提供技术积累。

The key problems were reviewed at home and abroad in recent years, including the cross-section design, the structural dynamic response, anchor cable vortex-induced vibration, driving safety, experimental test technique, and disaster prevention and mitigation of SFT. The key problems and further research direction existing in the research of SFT are summarized. The results show that: 1) It is necessary to comprehensively consider the cross-section type, floating-weight ratio, and arrangement mode of the section to ensure the stability of SFT; 2) The dynamic response of SFT and the vibration characteristics of anchor cable are mainly studied by numerical simulation and theoretical analysis. It is still necessary to develop physical model test technology; 3) It is necessary to build small SFT in feasible water conditions to make research on the physical SFT in the static waters, to lay a foundation technically for building large SFTs in complex sea conditions.

基于Vine-Copulas 模型的悬浮隧道水动力研究

Report：Using Vine-Copulas for hydrodynamic forces on a submerged floating tunnel (SFT)

 报告精华（Report Summary）

悬浮隧道（SFT）运行的水下环境存在许多不确定性。因此，研究波流共同作用下SFT上的作用力十分有意义。本研究考虑了变量之间的相关性，尤其是极端事件中的相关性。提出了一种可表示海洋气象变量间多变量联合分布的方法，如有效波高和周期、流速。Vine copula模型灵活性高、允许考虑变量间的复杂关系，将研究扩展到研究不同直径和淹没深度SFT的构造。在设计SFT和其他土木结构时，该方法可模拟更真实的场景。

A number of uncertainties arise from the underwater environment where the SFT will operate. Therefore, it is of interest to study the forces acting on a hypothetical SFT as a result of the combined action of waves and currents. In this study, we take into account the dependence between the variables of interest, especially during extreme events. Thus, we present a methodology that allows representing the multivariate joint distribution between metocean variables such as significant wave height and period, current velocities. Vine-copula models are proposed because of their flexibility and allow taking into account the complex relationships between variables. The study between metocean variables and their corresponding resulting forces is expanded to study different SFT configurations of different diameters and submergence depths. This methodology can be used to simulate more realistic scenarios when designing an SFT and other civil structures.

波流共同作用下悬浮隧道节段的水动力试验研究

Hydrodynamic experiment of submerged floating tunnel under regular wave and current actions during construction period

报告精华（Report Summary）

在大型波流水池中开展了138个规则波浪和波流共同作用工况下的模型试验，研究了波浪和波流相互作用对悬浮隧道动力响应和索力的影响规律。结果表明：波高、流速和波长与结构尺寸之比是影响悬浮隧道动力响应和索力的重要因素；试验中采用的多锚索布设方式，能较好地分配索力，减少因断索引起的安全隐患。本研究可为复杂海洋环境下，特别是波浪与海流相互作用下悬浮隧道的施工与控制提供参考。

A total of 138 regular wave and wave-current cases were conducted in a large wave-current pool during the experiments, and the influence of waves and wave-current interactions on the dynamic response of SFT and cable forces are discussed in detail. Results show that the wave height, current velocity, and ratio of wavelength to structure size are important factors affecting the dynamic response of SFT and cable forces. The multi-anchor cable arrangement used in the present experimental tests can better distribute cable force and reduce the potential safety hazard caused by cable breakage. This study can provide a useful reference for the construction and control of the SFT segment under construction in the complex ocean environment, especially under the interaction of waves and currents.

张力腿式水下悬浮隧道地震响应模拟 —以琼州海峡为例

Seismic Response of Tension Leg SFT—a Case Study in Qiongzhou Strait

报告精华（Report Summary）

本文以琼州海峡为例，开展悬浮隧道（SFT）在地震引起的水动力荷载、自重、浮力等共同作用下的结构静载、动力响应分析，并结合Rayleigh阻尼方程和Morison方程对附加阻尼计算进行探讨。结果表明：静力分析时最大截面弯曲正应力出现在两端与岩层嵌固处的底板；动力时程分析时，在地震波影响下轴向位移最大；地震作用下张力腿式SFT的拉索最容易出现问题，为确保结构的稳定性和安全性，拉索的动力性能需慎重考虑。

Report Summaries：Taking Qiong zhou Strait as an example, mainly considering the earthquake hydrodynamic loads, dead weight, load under the joint action of buoyancy, the SFT static load analysis, dynamic response analysis research. According to Rayleigh damping equation and Morison equation, the add damping of SFT is preliminarily determined. The results show that the maximum bending normal stress of the cross section occurs in the bottom plate embedded with the rock strata at both ends during the static analysis. In dynamic time-history analysis, under the influence of seismic waves, the displacement in axial direction is larger than other direction. The cables are the most likely to cause problems in tension leg SFT under the influence of earthquakes. Therefore, in order to ensure the stability and safety of the submerged floating tunnel structure, the dynamic performance of the cable system needs to be carefully considered.

基于水下爬壁机器人和深度学习算法的悬浮隧道表面病害检测

Surface disease detection of suspension tunnel based on underwater wall-climbing robot and deep learning algorithm

报告精华（Report Summary）

复杂波流条件下，悬浮隧道（SFT）表面易出现病害且不易察觉，急需开发一种高智能、低成本，无安全隐患的表面病害检测方法。深度学习算法能抗背景干扰，可承载海量数据，如何将其应用于水下图像，并搭配能快速无风险采集数据的水下爬壁机器人实现病害识别，尚需进一步研究。试验表明，水下爬壁机器人能克服波浪冲击影响，深度学习算法能准确检测表面病害，克服了海水对图像质量的影响，为SFT表面病害智能化检测提供新的可能。

Under complex wave and current conditions, the surface of submerged floating tunnel ( SFT ) is prone to disease and is not easy to detect. It is urgent to develop a surface disease detection method with high intelligence, low cost, and no safety hazards. Deep learning algorithm can resist background interference and can carry massive data. How to apply it to underwater images and match underwater wall-climbing robots that can quickly and risk-freely collect data to achieve disease identification still needs further study. Experiments show that the underwater wall-climbing robot can overcome the influence of wave impact, and the deep learning algorithm can accurately detect surface diseases and overcome the influence of seawater on image quality. This provides a new possibility for intelligent detection of SFT surface diseases.

挪威沿海公路E39号线项目中跨峡湾大桥技术的发展综述

Report：development in the Norwegian Coastal Highway Route E39 Project – A review

报告精华（Report Summary）

挪威公共道路管理局自2014年起对比约尔纳峡湾通道进行概念评估。峡湾宽约5公里，深约550米，传统桥梁或海底隧道在技术和经济上都几乎不可能。基于此，评估了新型浮式通道，包括浮桥、由张力腿支撑的悬索桥和带缆绳或浮筒的悬浮隧道。对技术、成本、风险、环境和其他因素进行全面评估，发现浮桥是该通道的最有利方案。值得注意的是，上述所有方案在技术上对比约尔纳峡湾均是可行的。换言之，开发的技术可用于其他峡湾跨越。

The Norwegian Public Roads Administration has started the concept evaluation of the Bjørnafjord crossing since 2014. The fjord features an approximately 5 km width and 550 meters depth, which means a traditional bridge or subsea rock tunnel will be almost impossible, either technically or economically. Based on this, novel floating concepts evaluated include floating bridge, suspension bridges supported by TLPs (Tension Leg Platform) and submerged floating tunnel with tethers or pontoons. It was concluded that a floating bridge will be the most favorable concept for this crossing, based on an overall evaluation of the technology, cost, risk, environment, and other factors. One important note here is that all the above-mentioned concepts are technologically feasible for the Bjørnafjord crossing, if not optimal. In other words, the developed technologies can be applied to other fjord crossings.

本文以千岛湖悬浮隧道（SFT）方案中的材料及环境参数为参照，采用三维有限元法，建立两端分别为简支、固定支撑、弹簧支撑的模型，分析了波浪荷载下SFT的动力响应。结果表明：当两端为弹性边界时，波浪作用下SFT中跨的横荡位移和边跨的垂荡位移介于两端简支与两端固支之间，而中跨的垂荡位移在三种边界条件下都很接近。三种边界条件下的侧弯弯矩差别明显，竖弯弯矩只在边跨有明显差距。弹性支撑边界的SFT锚索索力最大。

Report Summaries：Taking material and environment parameters of SFT design scheme in Qiaodao Lake for the reference, using three dimensional finite element method, through the establishing the different models of SFT with simply supports, fixed supports, spring supports in its both ends respectively, dynamic response under the action of wave-current is analyzed. The results show that when boundary conditions are elastic constraints, the swing displacements of intermediate span and the heaving displacements of two side spans are among the conditions of simple supports and fixed supports at both ends. The heaving displacements of intermediate span are very close under three different boundary conditions. The lateral bending moments of SFT with the three different boundary conditions have obvious differences. For the vertical bending moments, obvious differences are only observed on the two side spans. The cable forces of SFT with two end elastic supported boundary is larger than other boundary conditions.
