摘要
介绍了用瞬态法测定岩石、混凝土渗透系数的原理和方法。对两种岩性、两种混凝土试件进行了不同应力水平下的渗透试验，对渗透特性作了初步分析，得到了渗透系数与应力关系的试验公式。根据试验结果结合工程地质资料，对广州抽水蓄能电站二期工程采用不同钢支管长度的厂房区作了考虑和不考虑渗流场作用的三维渗流耦合分析。
The principle and method to mesure Permeability coef ficient of rock and concrete by instantaneous state approach are presented.The permeability tests with different stress levels are conducted for two kinds of rock and two kinds of concrete specimen,the tentetive analysis is made for permeability behaviour and the experimental formula related between permeability coefficient and stress obtained.According to test results in combination with engineering geology imformation,the three dimensional seepage flow coupling analysis with and without considering seepage flow field is made for machine hall area with different branch pipe length of stage Ⅱ work of Guangzhou Pumped Storage Hydroplant and some useful results for design are obtained.
