中文摘要：
建立室内人工边坡的降雨入渗模型,选取坡度为33.7毅的细砂边坡,在300mm/h降雨强度下进行试验.通过孔隙水压力传感器和自制含水率传感器监测试验中含水率、孔隙水压力的变化规律和分布情况及对边坡稳定的影响,分析边坡表层以下4cm及14cm深处的含水率、孔隙水压力变化和3个时刻坡体的含水率、孔隙水压力等值线图.分析结果表明,降雨入渗的整个过程中,下部的含水率、孔隙水压力都是最大的;边坡内部靠近底层的区域,其含水率和孔压的变化需考虑趾部及下部水分入渗的影响,因为这些影响会造成该区域的等值线密集.
英文摘要：
In this study, an indoor artificial slope rainfall infiltration model is built, fine sand slope is selected, an experiment is conducted with a gradient of 33.7 and a rainfall intensity at 300 mm/h. Pore water pressure sensor and homemade moisture content sensor are used to monitor the moisture content, change law and distribution situation of pore water pressure and their influence on slope stability. As the time goes by, the development process of slope failure, including flow, flow slide, block damage of sliding failure, is analyzed. Analysis is made on moisture content, changes of pore water pressure and isopleth map of slope body moisture content, and pore water pressure at three different moments at 4 cm and 14 cm below slope surface. The results show that in the whole process of rainfall infiltration, the moisture content and the pore water pressure in the toe are the largest; and near the bottom area inside the slope, the variation in moisture content and pore pressure is related to the influence created by water infiltration in the toe and bottom because the influence makes the isoline intensive in this area.
