摘要
采用Geostudio岩土工程有限元计算软件中Seep模块对某高速公路二级高路堤填方边坡在降雨条件下的路堤内部渗流状态变化趋势进行了分析,得到其变化规律;采用简化Bishop法对边坡安全系数进行了计算,得到不同降雨时间内边坡安全系数的下降趋势;同时对比分析了不同降雨时间内边坡潜在滑动面的位置,得到不同降雨条件下高路堑边坡在发生滑坡时最容易受损的位置。
The paper adopts the Seep model of Geostudio geotechnical engineering finite element calculating software to analyzes the tendency for the changes of the inner leakage status of the secondary high-fill embankment slope on some expressway, concludes its law of changes, adopts the simplified Bishop method to calculate its slope safe coefficient, concludes its downtrend of the slope safe coefficient in different rainfall time, compares and analyzes the potential location of the sliding surface in various raining time, and concludes the vulnerable location of the high-fill embankment under raining conditions.
