降雨与库水位涨落作用下边坡渗流场分析

The Seepage of Slopes Subjected to Rainfall and Up-down Stream

降雨与水位涨落会使渗流场产生剧烈变化，而渗流场计算是边坡稳定分析的重要依据。在分析比较各种渗流计算方法的基础上，采用饱和-非饱和渗流理论计算降雨与水位涨落作用下的边坡渗流场，分析了渗流场随时间的变化规律以及渗透系数k、水位变动速度v对边坡渗流场的影响，得出了浸润线在水位下降过程中各时刻的具体位置，以及水力梯度的分布情况，为边坡稳定性分析提供了可靠依据。

Seepage calculation is the foundation of stability analysis of slopes. Based on the comparison of various kinds of methods, this paper used the unsaturated transient seepage theory in calculating slope seepage. Through comparison of the seepage field in uniform slope, the evolution of seepage with time and permeability was studied.
