堆石渗流计算对于堵口合龙工程的成败与堤身的安全具有十分重要的意义,但目前生产实践中所采用的一些理论和方法,还不是十分成熟,近年来华东水院对这一课题进行了一些实验研究,本文拟对上述实验研究成果及堆石渗流计算所依据的基本原理作一粗浅介绍。一、渗流基本方程和其特性参数的确定当水流在由粗颗粒所组成的多孔介质中渗流时,水流运动的基本方程的普遍形式为 The calculation of rockfill seepage is of great significance to the success of plugging closure engineering and the safety of the bank. However, some theories and methods used in production practice are not yet very mature. In recent years, East China Water Institute has carried out this task A number of experimental studies, this paper intends to make a brief introduction to the above experimental results and the basic principles of rockfill seepage calculation. I. Basic equations of seepage and determination of their characteristic parameters The general form of the basic equation of the water flow when the water seeps through the porous medium consisting of coarse particles is
