摘要
采取弹塑性有限元程序,考虑基坑分步开挖的影响,对基坑开挖施工进行了模拟。通过分析开挖过程中土体的变形和应力状态及破坏状态,对开挖阶段基坑的整体情况进行了评价。
The program of elastoplastic finite element method (FEM) is adopted to simulate excavation of the foundation pit with the impact of staged excavation taken into account. Based on analysis of soil deformation, the state of stress and damages, the overall situation of the foundation pit during excavation is well appraised.
