基于FLAC3D对基坑开挖影响邻近建筑物的研究

摘要

Based on the excavation of the foundation pits of the underground space of some project,the paper establishes the FLAC3D finite ele-ment model,analyzes the influence of the foundation pit excavation on neighboring buildings,analyzes the numeric simulation of the excavation with and without supporting conditions,and achieves some meaningful conclusion.%以某工程地下空间基坑开挖为背景，建立了FLAC3D有限元模型，分析了基坑开挖对邻近建筑物的影响，通过对有支护条件基坑开挖与无支护条件基坑开挖的数值模拟分析，得出了一些有参考意义的结论。
