摘要
本文先简要介绍了当前研究裂隙岩石渗流的主要观点,以及解决混凝土坝坝基渗流的主要试验、计算方法。并针对当前整理渗压资料中存在的某些问题,重中了渗压资料的表示方法。最后,讨论了模拟研究与原型观测的结果对比情况,通过一些工程实例的对比分析指出,电模拟试验和数值计算虽各有所长,作为研究工程渗流问题的手段都是有效和可信的。只要原型的参数合适,即使把裂隙岩石当做多孔介质来考虑,也能取得与原型甚为吻合的结果。
The main opinions of the present study of seepage in fracture rock and the main methods of analogue model and numerical model approaches used for study on seepage through the foundation of concrete dam are reviewed in this paper. The method to show seepage to point to the problem which is met in the analysis of seepage information is restated. Finally, the comparison of analysis results on model study with the results observed in field is deseribed. By the examples of comparison of some engineering projeets, the electric analogue model and the finite element numerical model show their own advantages. The two methods as a means of study for engineering seepage problems are effectual and believable. Even if the fractured rock is treated as porous material, the study results shall be in accord with the observation in field when the prototypal factors are suitably selected.
