降雨是诱发边坡失稳破坏的主要原因。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。以都江堰市为研究区域,研究前期降雨、边坡体地下水位和渗流时间的关系,再结合滑坡启动的临界降雨模型,定量分析前期有效降雨对滑坡启动的影响。 |

Rainfall is the main reason that induces the slope instability and failure.Based on a slope hydrological model and combing with infinite slope stability calculation model,critical rainfall conditions of landslide starting are studied.Taking the City of Dujiangyan as the study area,the relationships of antecedent precipitation,groundwater level and the infiltration time are studied,and influences of antecedent effective rainfalls on landslides startup are quantitatively analyzed combing with critical rainfall model for landslide starting. |
