摘要:
|
基坑工程中支护体变形、地表沉降及坑底隆起情况是基坑安全情况的重要指标,结合天津港南疆焦炭泊位卸车坑及廊道工程,采用有限元软件PLAXIS建立计算模型,按照施工顺序分工况模拟基坑开挖过程,得出的基坑变形计算结果与实测值吻合较好,表明PLAXIS的计算结果比较可靠。

The wall deflection, ground settlement and heave of bottom induced by excavation in foundation pit are the important indexes of the safety of pits.A practical project is simulated with the finite element program PLAXIS by Step-construction. The calculation results agree well with the observed data. It shows that the result of PLAXIS is reliable.
