基于FLAC^(3D)的均质土坝最佳坡度分析

Slope Optimization Analysis of Homogeneous Earth Dam Based on FLAC^(3D)

针对利用FLAC3D可方便计算安全系数的特点,采用其内置FISH语言进行二次开发,编制了均质土坝最佳坡度优化程序,以利于边坡工程选择安全和经济的坡度,并对采用FLAC3D安全系数求解的方法、判据及程序实现的原理进行了介绍。以工程为例说明程序的使用方法,验证了该程序在一定程度上可预知边坡工程的安全性,计算结果可为边坡工程的设计和加固提供参考。

Aiming at FLAC^3D can calculate the safety factor expediently, use its internal FISH language to advance the second exploit,program composition of the slope optimization of homogeneous earth dam, which is useful to the decision of safe and economical slope in slope engineering. It was explained in detail about the method, criterion and programs realization principles in safety factor calculation of FLAC^3D. An example was used to show how to use the program and prove its effectiveness in anticipating the safety of engineering to a certain degree and the results will be good reference for the design and reinforcement of slope engineering.
