【摘要】 根据工程地质勘查资料及水文资料,运用流网法和渗流有限元法,对大坝坝基进行渗流对比分析。采用2种方法分析了不同防渗方案的防渗效果,比较了无渗控措施和有渗控措施下的压力水头的变化,结果表明有渗透措施的方案是合理有效的。更多还原

【Abstract】 According to the engineering geology investigation and the hydrological files,flow-net method and finite element method are adopted to carry on seepage analysis for dam foundation of Jiangkou hydroelectric power station.The seepage controlling effects exerted by different programs are analyzed by the two methods and the changes of the water pressure under seepage controlling and no controlling measures are compared,which shows that the seepage controlling program is effective.更多还原
