| 摘 要： | 针对大岩淌滑坡特殊的地理位置开展强降雨(或强雾雨)条件的入渗和地表漫流研究, 建立雨强与入渗、漫流之间的关系。然后,基于非饱和渗流理论,采用有限元方法来分析大岩淌滑坡在降雨期间的渗流、应力、位移与安全状态,并在稳定性计算中引进强度折减法计算滑坡的安全系数。

| Abstract: | A coupling between infiltration and ground-surface overflow was studied in the condition of heavy rainfall(or atomized rain caused by the flood discharge) for the special geologic setting of Dayantang landslide,and the relationship between the intensity of rainfall and infiltration,overflow established.Then,on the basis of the unsaturated seepage theory,the seepage,stress,displacement and state security were analyzed during the rainfall by FEM,the safety factor of slope was calculated by the strengthreducti... |
