摘要
介绍了FLAC3D的基本原理及其求解过程;通过对某基坑进行三维数值模拟,得出了土钉支护基坑的位移场和土钉受力规律,说明了使用数值方法模拟基坑开挖的有效性,并为使用极限平衡法计算土钉支护基坑安全系数时土钉抗力取值提出了参考意见。
The basic theory and calculation procedure of FLAC3D are introduced; by three dimensions numerical simulation of a foundation pit, the regulation of displaeement field of soil-nail supporting foundation pit and force-bearing of soil-nail are eoncluded; the efficiency of using numerieal simulation to excavate foundation pit is illuminated; and a reference for the value of soil-nail resistance is given when use limited equation method to calculate soil-nail supporting foundation pit safety factor.
