基于室内试验的降雨型滑坡机理研究
Research on mechanism in rainfall landslides based on laboratory test

结合福建山区典型降雨型滑坡特点，建立室内人工降雨滑坡试验模型，从降雨强度入手，模拟降雨型滑坡的发生过程，探求降雨强度对降雨型滑坡的影响机理. 利用有限元法建立考虑滑坡因子的数值模型，进行渗流和稳定性分析，得到降雨强度与滑坡启动时间的关系公式，数值仿真结果与试验结果基本一致，所得结果有益于降雨型滑坡机制的深入研究.
According to the landslide characteristics occurring in Fujian mountain area，laboratory artificial rainfall landslide test model was built，simulated occurrence process of rainfall landslides in different rainfall intensities，explored the effects of rainfall intensity on landslides mechanism. At last，the relationship between rainfall intensity and sliding time was calculated by using finite element method. The numerical simulation result was in good agreement with experiment. The results are valuable to further probing into the rainfall landslides mechanism
