| 摘 要： | 对万州区滑坡滑带土干重度的86个测试数据进行拟合优度检验,发现多种传统的检验方法都既可以接受正态分布也可以接受对数正态分布.在传统检验方法失效的情况下,引入了有限比较法,确定了干重度的最优概率分布为正态分布,并用统计模拟的方法分析了有限比较法选中真实分布的概率.

| Abstract: | To determine the probability distribution of dry unit weight of landslide zone soil in Wanzhou area,this paper firstly apply several traditional goodness of fit methods,and find that both normal distribution and logarithmic normal distribution are acceptable to a variety of traditional goodness of fit methods.In order to determine the optimal probability distribution of dry unit weight,finite contrast method is proposed.Statistical simulation was used to analyze the probability of choosing the real distribu... |
