中文摘要：
基于正态信息理论,给出了路基沉降概率分布的拟合方法,并利用精度较高K-S检验法验证了该方法的正确性。将Beta分布引入路基沉降模糊失效事件的隶属函数中,解决了常用隶属函数存在的不足。同时,利用模糊可靠度理论,给出了路基沉降模糊可靠度的计算公式。最后通过工程实例验证了本文方法的有效性。
英文摘要：
Based on normal information spread theory, a new method is presented to fit the probability distribution of settlement of subgrade, and the correctness of the Kolmogorov-Smirnov testing method. Beta distribution is chosen fuzzy event of settlement for subgrade, which presented method is verified using as the membership function of the solves the deficiencies of common membership function Meanwhile, the fuzzy reliability index of settlement for subgrade is calculated according to fuzzy reliability theory. Finally, the validity of presented method is verified through case study.
