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 numbers 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.
