降雨是诱发边坡失稳破坏的主要原因,本文以坡地水文模型为基础,结合无限边坡稳定计算模型,研究降雨条件下边坡启动的临界降雨条件。通过工程算例表明:降雨量与边坡体稳定系数成反比;滑坡启动的临界降雨量随边坡坡度的增大而减少;随边坡土体内摩擦角的增加而逐渐增加,此分析对降雨型滑坡的研究有借鉴性的意义。 |

As rainfall is the main reason that induces the slope instability and failure,this paper combined the slope hydrological model and the infinite slope stability model to study rainfall for starting condition of landslide.the project example shows that the rainfall is in an inversely proportional relationship with the slope stability factor;the critical precipitation linearly increases as the friction angle increase and decreases as the slope gradient increase.This study is of reference value for the rainfall-induced landslide. |
