摘要

摘要: 在对多孔介质中的饱和-非饱和渗流数学模型简要分析的基础上,对影响渗流有限元计算分析结果的一些参数选取方法进行讨论,如非饱和土的水土特征曲线、水力传导系数及毛细水头等。利用相关程序对降雨条件下的基坑边坡内部渗流场进行模拟,分析地下水位线、坡体饱和度、压力水头及坡体内不同位置处的渗流速度随降雨时间的变化规律。模拟结果与实际情况比较吻合,可为基坑边坡稳定性的分析提供参考依据。

Abstract: On the basis of briefly analyzing the mathematical model for the saturation -unsaturated seepage flow of porousmedium, the selcetion method of such parameters affecting the seepage finite element calculation result as water and soilcharacteristic curve, hydraulic conductivity and capillary water pressure is discussed. In the end, the relative program isused to simulate the seepage field inside the excavation slope during rainfall, and the change law of the underground watertable, saturation of the slope, pressure head and seepage velocity of different positions inside the slope is analyzed. Thesimulation results are rather in agreement with the practical condition, which can provide the evidence for the stabilityanalysis of the slope.
