摘要
为研究不同非饱和参数对考虑蒸发效应的边坡的温度、湿度及其稳定性的影响,以广西南宁某边坡为研究对象,利用Geo-studio软件进行有限元计算,得到边坡内部不同监测点孔压、体积含水率、温度及边坡安全系数变化规律。结果表明,降雨过程中孔压呈现不断增大的趋势;体积含水率在降雨过程中先急剧上升,后缓慢上升;边坡内部温度变化趋势与气候条件下的温度变化较为一致;安全系数随降雨呈现逐渐下降的趋势。
In order to study the influences of different unsaturated parameters on the temperature, humidity and stability of slope considering evaporation effect, the finite element calculation is carried out by Geo-studio for a slope in Nanning,Guangxi, and the variation rules of pore pressure, volume moisture content, temperature and slope safety factor at different monitoring points in slope are obtained. The results show that:( a) the pore pressure increases continuously during rainfall;( b) the volume water content increases sharply in the process of rainfall, then increases slowly;( c) the variation trend of internal temperature of slope is consistent with the change of temperature under climatic conditions;and( d) the safety factor is gradually decreased with rainfall.
