雾化雨入渗影响下岩质边坡的流固耦合分析

借鉴不饱和渗流的研究方法，参考考虑雾化雨入渗的数学模型和应用有限元软件ABAQUS，分析了雾化雨入渗影响下边坡位移场和渗流场的变化，以及雾化雨入渗对岩体高边坡稳定性的影响。将该方法应用于某水电站大型岩体高边坡工程，得到具有重要工程指导意义的结论和建议。结果表明，雾化雨入渗使得坡体发生了较为明显的变形，且入渗量越大边坡的变形越大，应加强坡面的保护，最大限度地减小雨水入渗，降低雾化雨入渗对边坡的影响。

The fluid-structure coupling analysis of rock slope under the influence of atomized rainfall infiltration

Referring to the research method of unsaturated seepage and the mathematical model due to atomized rainfall infiltration, using the finite element program ABAQUS, the change of slope’s seepage field and displacement field under the influence of atomized rainfall infiltration is analyzed. The stability of high rock slope due to atomized rainfall infiltration is analyzed, and this method is used in rock slope of a certain hydropower station; the instructional conclusion is gained. Computed results show that slope’s distortion is big because of atomized rainfall infiltration; and the distortion is bigger the infiltration quantity is bigger. So, we should reinforce the protection of slope and try my best to reduce rainfall infiltration and reduce the influence of atomized rainfall infiltration.
