摘　　要：以工程地质分析法为基础，针对边坡稳定性工程地质评价时评价指标多层次及多人参与的特点，应用系统工程与模糊数学知识，建立了岩质边坡稳定性多人多层次模糊综合评价模型。从影响边坡稳定性因素的构成关系入手，构造了描述边坡稳定性综合评价的评价指标多层次有序评价树（ＭＯＥＴ）结构，建立了ＭＯＥＴ中评价指标的知识量化方法：包括４种隶属函数与集成式指标权重获取方法，给出了基于知识的模糊推理算法及其计算机程序框图，研制出岩质边坡稳定性多人多层次模糊综合评价系统（ＳＭ２ＦＣＥＲＳ２）。实例证明该系统是有效的。In the paper, the theories of System Engineering and Fuzzy Mathematics are applied to construct a multiperson and multilayer fuzzy comprehensive evaluation model for rock slope stability according to the characters that the evaluation indexes are multilayer and that the evaluation process is completed by many people in engineering geology evaluation of slope stability.The main factors affecting the stability of rock slope are analyzed, a structure of multilayer ordered evaluation tree (MOET) is set up for the comprehensive evaluation of rock slope stability, and the quantification methods are suggested for evaluation indexes of MOET which include four kinds of subordinate functions and an integrated index-weight determination system. then a fuzzy reasoning algorithm is formulated on the basis of slope engineering knowledge, a computer program flow chart of the whole comprehensive evaluation process and a computer program system for multiperson and multilayer fuzzy comprehensive evaluation of rock slope stability(SM 2FCERS 2) ard developed. Finally, an example is used to show the effectiveness of the system.
