中文摘要：

基于最大值的原则，熵被采用分析在 geomembrane 和小粒的材料之间的接触力量的随意的一个概率的方法。接触力量分发根据建议方法是指数的，谷物尺寸是影响接触力量的分发的最重要的因素。建议方法然后被一系列实验室实验作为小粒的材料和一个很薄的压力用玻璃祷告和卵石验证，显示那部电影第一在给一个可靠方法测量在每个接触点的接触力量的这些实验被使用。

英文摘要：

A probabilistic method based on principle of maximum entropy was employed to analyze the randomness of contact force between geomembrane and granular material. The contact force distribution is exponential according to the proposed method and the grain size is the most important factor that affects the distribution of contact force. The proposed method is then verified by a series of laboratory experiments using glass beads and cobbles as granular material and a very thin pressure, indicating that film is firstly used in these experiments which give a reliable method to measure the contact force at each contact point.
