摘要
通过考虑降雨条件下的室内边坡试验,研究了水流在边坡中的入渗特征及降雨入渗对边坡稳定性的影响,并通过数值模拟方法分析了水分的运移规律。研究结果表明:在一定水头的入渗过程中,边坡的安全系数不断降低,浸润速率不断变慢。数值模拟和试验结果非常接近,且更为直观地反映雨水的入渗过程。
The slope infiltration characteristics and influence of rainfall infiltration to the stability of slope are researched by considering the indoor slope test under the condition of rainfall. The moisture mi- gration rule is analyzed by the numerical simulation analysis method. The result show that in the process of certain head infiltration, the safety coefficient of slope is decreased constantly, the infiltration rate is slowed constantly. The numerical simulation results is consistent with the test results, and the rainwater infiltration process is reflected by the numerical simulation results more directly.
