Based on the basic principles and means of fuzzy mathematics,with the main internal and external divisors of the stability of landslide under seismic load,the model of slope stability was established for fuzzy comprehensive assessment.By establishing slope stability evaluation index system,combining analytical hierarchy process with fuzzy mathematics theory,and making use of importance order to obtain the weight of every index,the fuzzy mathematics method was used to make a comprehensive evaluation of the slope stability under seismic load.This method is straightforward and is simple to be programmed.The result indicates that the model makes the slope stability evaluation more authentic,more scientific and more coincident than practical situation.
