摘要
通过室内实验的方法,针对水力梯度对渗透系数的影响展开研究。实验筛分出粗砂、中砂、细砂分别进行不同水力梯度的渗流实验,并对每组实验数据进行分析、整理,通过计算机作图等手段研究水力梯度与渗透系数二者之间的关系。得到渗透系数随水力梯度变化的规律。
The hydraulic conductivity is an important hydrogeological parameter. The experiment is conducted on the hydraulic conductivity to find the effect of hydraulic gradient through the laboratory test. In the experiment the coarse sand, the medium sand and the fine sand are sieved out to conduct the different hydraulic experiments. Collecting and organizing the data are to develop the relationship between the hydraulic conductivity and the filtration parameter through the computer. This article develops the rule of hydraulic conductivity which is changed with hydraulic gradient, in order to explore the variation of the hydraulic conductivity under the normal temperature and pressure.
