| 摘 要： | 渗流是影响岩土工程边坡稳定性的重要因素，对不同工况下岩土体边坡地下水渗流规律进行数值模拟，弄清其动态变化规律，对于边坡稳定性分析、支护设计、工程防排水措施的制定等都有重要的意义。以龙滩水电站左岸进水口边坡为研究对象，通过免疫进化规划算法，得到了边坡岩体渗流场参数。在此基础上，对洪水期、枯水期情况下地下水渗流状态进行了数值模拟，通过对比分析，研究了不同河床水位情况下地下水渗流变化规律，从而为边坡稳定性预测奠定了理论基础。

| Abstract: | Seepage is one of the most important factors which affect geotechnical engineering slope stability. It is significant to study seepage and dynamic change laws under different regimes in rock and soil slope for stability analysis, support design, and engineering water-proof and drainage projects. Using immune evolutionary programming, seepage parameters of left-side rock slope of Longtan hydropower station have been obtained from back analysis. Based on the back analysis of seepage parameters, ground water flow in slope have been simulated under low-water and high-water periods. By comparing the results, change laws of water head under different periods have been summarized, thus providing theoretical basis for slope stability analysis. |
