溶洞地基稳定性模糊综合评价法综述

Fuzzy synthetic evaluation on the stability of the foundation to karst cave

近年来,模糊综合评价法越来越多地用于溶洞地基稳定性分析中,并取得了良好的效果。介绍了溶洞地基稳定性模糊综合评价法的运用现状,并在模糊综合评价基本原理的基础上,对溶洞地基稳定性指标体系的确定做了详细的叙述,同时简述了隶属函数形式与权重值确定的方法,对影响溶洞地基稳定性的突出因素做了简单的概括。

In recent years,fuzzy synthetic evaluation has been increasingly used in the stability analysis of the foundation to karst cave,and attained good effects.This article introduces the actuality of fuzzy synthetic evaluation on karst foundation.Based on the basic principle of the fuzzy synthetic evaluation,it describes the establishment of indicator system on the stability of the karst cave foundation in detail.Then it gives a determining method to determine the subjection function and factor weights.At last,it simply summarizes the priority factors in affecting the stability of the foundation to karst cave.
