| 摘 要： | 绝大多数岩质边坡的破坏均是由于地下水在裂隙中的渗流而引起,岩体的渗透特性对边坡稳定性的影响是不可忽视的。文章介绍了裂隙岩体渗透系数的确定方法及边坡的稳定性分析方法,并基于3D-FLAC模拟分析,探讨了岩体渗透系数对边坡稳定性的影响等问题,研究表明,随着岩体渗透系数的增大,孔隙水压力增大,有效应力减小,边坡的安全系数降低。

| Abstract: | It is the main reason for failure of rock slope that the rock crack seepage flow of underground water,the rock seepage character has a significant influence on slope stability.The research of rock permeability coefficient and analysis methods of rock slope stablity are introduced,the influence of rock permeability coefficient on slope stablity is studied.Base on the numerical analysis by 3D-FLAC,the influence of rock permeability coefficient on slope stablity is studied.The result shows that when the pore water pressure increases and the effective stress reduces,the permeability coefficient reduces. |

| Keywords: | permeability coefficient slope stability safety factor |
