摘要

介绍了FLAC3D的基本原理及其求解过程。通过对某边坡进行数值模拟，对比分析了此边坡在锚杆支护前后水平位移等值线图、竖直位移等值线图及安全系数的变化，说明了FLAC3D模拟边坡开挖以及支护的简便性和锚杆对边坡稳定性的作用效果。

Abstract

Based on the theory and calculation procedure of FLAC3D

two models are established

one for unreinforced slope

other for reinforced slope

some differences are displayed in horizontal displacement contour maps

vertical displacement contour maps and safety factors. The results show that the grouted bolts increase the safety factor and restrict the horizontal displacement; and the contours show the position of the largest displacement

the position of the slip plane and the slip vector so as to offer reference for guiding engineering construction.
