摘　　要：以正交表L9(34) 设计9 组试验,进行了27 次( 每组3 次重复试验) 为探讨加筋土陡边坡可能的状态和其相关因素的相关关系室内模型试验,并以所得的数据为依据,进行方差分析、误差分析,确定各影响因素对边坡状态影响程度的排序,再结合层次分析原理(AHP 法) 得出各影响因素的权重,进而应用模糊聚类方法对模型试验的边坡进行状态评定分析,并将所得结论和试验结果对比,成功地找到了加筋土陡边坡状态评定的量化指标。对加筋土边坡的破坏模式划分和应用的合理性进行了讨论。Twenty seven model tests designed through orthogonal principle have been performed to search for the relationship between the performance of geogrid reinforced steep slope and its affecting factors. Based on the test data, the affecting factors have been put in order according to their contribution to the performance of reinforecd steep slope by error analysis and variance analysis, meanwhile the factor's weight has been obtained by the aid of AHP(Analytical Hierarchy Process) method, succeeding in finding out the measurement index to evaluate the performance of reinforced steep slope by applying the method of fuzzy cluster. The rationality of the classification and utilization of the failure mode has been discussed and some suggestions have been pressented.
