| 摘 要： | 结合天津港地区以淤泥质为主的工程地质条件，构建引桥式接岸结构的ANSYS有限元数值模型。根据PDS模块抽样结果建立基于桩基承载力、胸墙一引桥连接点强度和结构位移等3种失效模式下的响应面方程，计算各随机变量影响结构可靠度的灵敏度和不同失效模式下接岸结构的可靠度，提出可供接岸结构优化设计参考的相关建议。

| Abstract: | Based on the engineering geological condition of muddy coast of Tianjin Port, ANSYS finite element numerical model is built to analyze trestle-type shore connecting structure. On the basis of PDS module sampling results, response surface equations are created against three failure modes, which are the limiting states of the bearing capacity of foundation pile, the structural displacement and the tie-point strength between breast wall and approach trestle. Calculation is made to get the sensitivity that random variable influences structural reliability and the reliability of shore connecting structure under different failure modes. Relevant suggestions were raised to optimize the design of shore connecting structure. |
