| 摘 要： | 三峡船闸是世界上最大的船闸。该地区断层及节理比较发育，且具有一定的随机统计性，它对岩体力学性质起重要的控制作用。为了研究节理倾向的概率分布特征，本文引入以Bayes 最小熵优度比较检验为基础的概率分布的改进Bayes 统计推断方法，基于三峡工程永久船闸节理岩体3373 条结构面的实测参数，就对岩体力学性质起控制作用的各组结构面的倾向参数的概率分布进行了研究。文章最后还讨论了推断的最优分布参数，估计了结构面参数的检验误差范围。

| Abstract: | The shiplock of the Three Gorges Project is the largest one in the world. Faults and Joints in rockmass are more developed of in the project area and affect the mechanical properties of rockmass. For study the distribution character of joint dips, an advanced Bayes method is used to infer the probability distribution function(PDF)of joint dips parameters in rockmass in the paper. Based on 3373 Joints in the rockmass for the permanent shiplock of the Three Gorges Project, the PDF of dip parameters are analysed by using advanced Bayes method and the errorstested are in permissible limit. |
