摘要

工程上将满足一定条件下的黏土层介质视为隔水层。通过模型试验的方法，对黏土层为不透水层的确定方法以及黏土层内部的水压力分布规律进行了研究。通过试验分析得出了某给定黏土层为隔水层的特定条件：即找出了黏土层的厚度、渗透系数及层上水头高度三者的关系和给定黏土层的起始水力坡降，得到了黏土层内已渗透水部分的水压力分布规律。试验结果对工程实际具有一定的指导作用。

Abstract

The clay layer substance is regarded as water-resisting layer in certain condition in engineering. Through the methods of model test

experimental research was carried out for determining methods of whether the clay layer is water-resisting layer and the distribution regularity of water pressure inside. Certain condition of clay layer for water-resisting layer is found out according to the experimental results; that is found out the relationship among the thickness of clay layer

permeability coefficient and water table height on the clay layer

initiative hydraulic slope is gained for certain clay layer

water pressure distribution regularity is also gained inside the clay layer which has been infiltrated water. Experimental results have some guidance effects for the practical engineering.
