摘要

讨论了润扬长江大桥北锚碇基础施工开挖中50 m特深基坑的三维非线性有限元分析，介绍了工程的有关情况，讨论了其计算模型和参数取值，给出主要计算结果并对有关影响因素进行了分析，在此基础上对该基坑支护的设计作出评价，最后结合施工结果讨论了计算分析的可靠性。

Abstract

The nonlinear three-dimensional finite element analysis of the 50m deep excavation support during the foundation construction of the north anchor in the Runyang Yangtze River Bridge project has been carried out and discussed. After a brief description of the relevant facts

the numerical model and the input parameters are proposed. Calculations are performed considering various influence factors. Based on the analyses the feasibility of the support system design is evaluated. The outcome of the execution proved the proceeding evaluations.
