摘　　要：以天津市某一深基坑工程为例,基于FLAC-3D数值分析软件,进行了不同开挖时间和空间的数值模拟计算,并与开挖监测结果进行对比,分析了深基坑开挖过程中围护结构变形、支撑轴力、坑底回弹及工程桩承载性状等参数的时空效应。Taking a deep excavation in Tianjin for example, the numerical simulations are progressed under different excavation time and space basing on the numerical analysis software FLAC - 3D in this paper.The measured data is compared and the changes of horizontal displacement of wall, supporting force, bottom soil upheaval, and bearing capacity of piles during excavation with time and space were analyzed

关 键 词：深基坑工程 时空效应 数值分析
