摘要
介绍了空间效应在天津市区某工程基坑开挖过程中的应用,观测围护结构的变形和坑外建筑物的沉降,并用有限元分析空间效应对基坑开挖的影响,结果表明基坑开挖具有明显的空间效应作用,合理利用这种空间效应,将有效的减少围护结构的变形,同时减少开挖对周围环境的影响。
Spatial effect was applied to foundation excavation in Tianjin. Deformation of the support structure and the building settlement near the foundation pit were observed, and Finite Element Analysis was used to simulate the spatial effect on foundation excavation. The results show obvious spatial effect during excavation. Spatial effect used reasonably can reduce deformations of the support structure and effects on environment around the foundation.
