中文摘要:

降雨入渗直接影响土质边坡渗流场分布,是土质边坡失稳的主要诱发因素。通过降雨强度、水力坡度、渗流量等因素对土质边坡发生滑动破坏部位的渗流场影响的分析,求解降雨入渗与边坡失稳的内在联系。基于渗流场方程和温度场方程原理的比较分析得出可以运用温度场模拟渗流场变化规律,运用Adina有限元分析软件中温度场对边坡降雨作用进行流固耦合模拟,从而确定不同降雨条件下边坡渗流速度和渗流量的变化规律。对滑动破坏部位的分析中得出:滑坡前缘水力坡度变化大渗流量高易发生渗透破坏,滑带区域的渗流速度变化明显,研究了边坡降雨入渗的渗流方向。本文对滑坡的降雨诱发因素和滑带位置的渗流场变化规律提供了新的视点,为进一步滑坡的研究提供了参考。

The rainfall infiltration has a significant influence on the seepage field of landslip,which is the important reason of slope failure.Through the analysis of rainfall intensity,hydraulic grade and seepage discharge to the seepage field and the stability of soil slope,the paper got the inherent relation between the rainfall infiltration and slope instability.Based on the identical theory of equation of seepage field and the temperature field,it present a computer simulation of Fluid-solid interaction using A...
