| 摘 要： | 库岸高填方路堤的稳定性受库水位涨落影响较大,同时,采用不同的土水特征曲线,边坡的稳定性计算结果也不相同.计算了当边坡土体的饱和含水量、饱和渗透系数相同时,3种不同的土水特征曲线对应的边坡安全系数,并得到了以下结论:土水特征曲线对考虑非饱和特性的土质边坡安全系数影响较大;采用黏土土水特征曲线计算出的边坡安全系数较粉土和砂...

| Abstract: | The stability of high embankment reservoir bank is influenced immensely by the fluctuations of water level.At the same time,slopes which have different characteristics of soil water characteristic curve have different results of stability calculation.The slope safety coefficient is calculated in this paper,which is in the same saturated soil water content and saturated hydraulic conductivity but is different in soil water characteristic curve.There are three types of curves.The following conclusions are rec... |
