运用FLAC3D对一个简单土坡算例进行计算,分别运用目前常用的收敛判据、位移突变和塑性区判据来求得安全系数,这三个判据计算出的结果相近且都与FLAC内置fish语言求解安全系数的答案接近,说明在今后的具体运用中,以塑性区为判据会得到比较保守的安全系数,而采用监测关键点的位移相对比较直观精确,同时基于以上判据,综合考虑其他判据,使各判据在使用中尽量提高精度,这样才会得到比较可靠的结果。

FLAC3D was used to analyzed a simple slope,the convergence criterion,displacement mutation criterion and plastic zone criterion which were now commonly used to seek safety factor separately.the calculate results of the three criterias were similar,what,s more,they were close to the tranditional answer of safety factor which was solved by built-in language.It was illustrated that the plastic zone would be more conservative as the criterion of the safety factor,but by monitoring the displacement of key points was relatively straightforward precision.In order to maximize the accuracy,we should take the other criterias into account and at the same time based on the above criterias in the future specific using.This would get more reliable results.
