摘要
用空间有限元法研究了基坑开挖过程中周围地表沉降量的分布型式、分步开挖效应及空间效应,与按二维平面问题分析的结果进行了比较分析,得出了一些有益的结论,供工程实践参考.
Finite element method (FEM) was used to analyse the distributing type, step- excavation effect and spatial effect of ground settlement around the excavation, and the results calculated with 3 - D FEM and 2 - D FEM were compared. Finally, some useful conclutions are obtained to direct the engineering practice.
