摘　　要：云南祥临公路边坡地质条件复杂,岩土性能差,易滑地层分布广,中大型滑坡滑带土大多为含碎石粉质黏土。采用随机统计法和随机-模糊法对此类滑带土的试验数据进行统计分析,得到祥临公路沿线该类滑带土的抗剪强度指标的概率密度函数,给出其置信区间,并对某处典型滑坡采用4种不同统计方法进行具体分析,并将分析结果加以对比,从而对类似地质条件的滑坡治理起到借鉴作用。The geological conditions in Xiang-Lin Road in Yunnan Province are complex with poor rock quality, far-ranging slopes and numerous clayey gliding mass containing much reduced stones.The test data of this kind of gliding mass are analyzed by the random statistic method and random-fuzzy method. The density function of the shear strength about the gliding mass is worked out firstly. Then the shear strength of the representative slope is acquired in four different ways. At last, the comparison is made between the statistic results so as to get the best indicator.
