深基坑隆起稳定性的模糊可靠度参数分析

通过模糊概率与可靠度分析法相结合，引入深基坑抗隆起破坏分析的普朗特尔公式，建立了两随机变量的模糊可靠度简化模型，对隆起破坏进行了模糊可靠度评价，并对插入比、围护结构长度、地面超载、粘聚力、内摩擦角等参数进行了分析。通过实例，计算了深基坑隆起失稳的模糊破坏概率和模糊可靠度，验证了简化计算模型的实用性。结果表明，隆起破坏的失效概率与内摩擦角呈指数函数递减关系，模糊随机方法能够合理地反映基坑的实际稳定性。

Analysis on Stability Parameters of Expansive Soil Slope

Stability control of expansive soil slope is a major difficulty for engineering construction.In this paper,through discussing the stability of expansive soil slope,the unstable mode of expansive soil slope is summarized to shallow surface damage and overall arc damage,expansive soil slope is divided into weathered layer and unweathered layer for stability analysis,and the method of parameters selection for stability calculation is put forward.According to the case study of Hefei-Liu' an Highway,the stabilit...
