| 摘 要： | 运用饱和-非饱和渗流有限元法模拟降雨条件下饱和-非饱和土质高边坡暂态渗流场的变化情况,本文对降雨边界的处理方法加以改进,使其适用于土质高边坡渗流场的计算.对砂箱模型和土质高边坡模型的计算结果表明:所提出的边界条件的改进足可行的;雨水入渗引起土壤基质吸力大量丧失,降雨初期基质吸力丧失最快;当降雨强度相对土体入渗能力较大时,基质吸力的丧失速度主要取决于土体自身的入渗能力.

| Abstract: | Based on the finite element method of the saturated-unsaturated seepage,the saturated-unsaturated transient seepage field of high soil slope is simulated under the condition of rainfall.An improvement of processing of the rainfall infiltration boundary is proposed,and the improved processing is suitable for calculation of the saturated-unsaturated transient seepage field of the high soil slope.The calculation results of sand tank model and high soil slope model show that the method proposed in this paper is... |
