| 摘 要： | 在工程地质问题中许多现象是不确定、且具有随机分布的特性，而这种随机分布特性往往可以采用某种形式的密度函数来描述。采用Ｘ２检验假设分布有效性是一个重要的方法，采用该法可以获得观测数据最佳拟合的概率模型，通过自编程序可以同时检验多种概率密度函数并选取最佳模型。本文将介绍这一方法，并通过一个实例加以说明。

| Abstract: | The phenomena with the characteristic of undetermined, random distribution in the enginneering geology problem that is often run into some kind of characteristic of random distribution. This generally can be described by some probability density function. It is an important method by means of chi square test validity of assumed distribution, the best fitted probability distribution model for the observed data can be obtained in this way. The method of chi square test will be introduced and a case study is presented in this paper. |
