摘要
水库建成蓄水后,为满足防洪和发电的要求,水位将在最低正常水位和最高正常水位之间反复升降,库水位的变动很可能诱导库岸变化的失稳。因此,有必要对动态水位诱导下库岸边坡稳定性进行分析。采用数值模拟方法,结合小浪底水库运营方式,分析不同库水位升降及不同升降速率下库岸边坡稳定性演化规律,研究成果为库岸的稳定分析及防护提供了有益的依据。
After impoundment, the reservoir water level will fluctuate in normal lower and higher water level in order to meet the requirements of flood control and power generation, which will induce stable bank slope develop to instable probably. Therefore, it＇s necessary to make systematic research on the stability of landslide because of dynamic water level. In this paper, evolution of bank landslide stability rules in different water level fluctuation and different lifting rate are analyzed by numerical simulation combining with the Xiaolangdi Dam reservoir operation. The research results can provide useful basis for the stability analysis and protection of bank landslide.
