摘要

保土准则是土工织物反滤准则的重要组成部分，但目前的设计准则保土有余，透水不足。介绍了无纺土工织物的两种孔洞分布曲线，计算了土颗粒透过织物的概率。在理论分析的基础上，提出了一种概率保土准则。该准则对土体中的骨架颗粒和小颗粒透过织物的概率分别加以限制，既能保持土体稳定，又能防止淤堵。

Abstract

Retention criterion is an important part of filter criteria for geotextile

however

the prevalent design criteria is too strict for retention of soil particle and not enough for permeability criterion. Two different opening size distribution curves of geotextiles are introduced; and the probability that soil particles pass through nonwoven geotextile is calculated. Based on theoretical analysis

a probabilistic retention criterion is proposed. The new retention criterion restricts the probabilities that both coarse particle and fine particle pass through nonwoven geotextiles; and it can not only keep the stability of soil

but prevent the clogging of geotextile.
