库区土质边坡稳定性分析

摘要

The Fellenius method is applied to deduce the safety factor formula for reservoirrnembankment slope with circular slip surface, which can reflect the influence of water level.rnFurthermore, the equations for determination of critical slope and the location of mostrndangerous surface are proposed. These results are practical to the prediction of embankmentrnslides.%本文首先对国内部分水库边坡滑坡的特点进行了初步分析，通过对库区边坡条件进行必要的概化，基于Felleniusrn方法导出了受库区水位影响、具有圆弧滑动面的边坡稳定系数理论公式，并进一步从理论上确定了库区边坡临界与最危险滑rn动的位置及规模.研究成果可用于预测及治理库区滑坡.
