岩溶地面塌陷危险性模糊评价方法

岩溶地面塌陷危险性评价是一个复杂而亟待解决的问题,本文针对岩溶地面塌陷危险性评价的特点,在综合考虑影响岩溶地面稳定性的多种因素的基础上,引入系统层分析方法和多级模糊评价方法,并以正态函数为隶属函数,以实数的加乘运算作为合成运算规则,建立了岩溶地面塌陷危险性评价的二级模糊评价模型,并将评价结果分为:稳定、较稳定、较不稳定和不稳定4级。应用于广州市某建设场地地质灾害评估工程,结果表明该方法具有良好的可靠性。

FUZZY EVALUATION METHOD FOR KARST COLLAPSE RISKS

The evaluation of fkarst collapse risks is a complex and important issue.After normal school function is accepted as a subjection function,and the real number’s addition and multiplication is occupied as composite role.Aiming at the evaluation of karst collapse risk,the model for the karst collapse risk is established with two stage fuzzy synthetic judgment theory and the analytic hierarchy process,.There are four evaluation results,stability,relative stability,relative instability,instability.From application to some engineering practice in Guangzhou,the results show that the method is reliable and has significant engineering and academic values.
