中文摘要：
针对润扬大桥北锚碇基础地下连续墙连续开挖施工过程,基于ADINA三维有限元分析软件,建立了地下连续墙开挖三维有限元仿真计算模型。对地下连续墙基坑开挖过程中的水平位移及基坑中心隆起进行了模拟计算,并与实测结果进行了比较,同时对有关影响因素进行了分析。计算结果表明,ADINA计算模型能够较好模拟基坑开挖过程及其变形,最后结合施工结果讨论了计算分析的可靠性。
英文摘要：
In light of the diaphragm wall excavation process for foundation anchorage of Runyang bridge,we established 3-D FEM model based on ADINA to simulate continuous excavation of the diaphragm wall.The horizontal displacement and the uplift at the center of foundation pit and the respective influential factors were analyzed,and compared with the measured data.The results show that the ADINA can simulate pit excavating process and its displacement accurately.At last,we mainly discuss the reliability of the computational result based on the construction results.
