摘　　要：大型灾害性滑坡预测问题是岩土力学的重要的应用性研究课题。对下铺子滑坡进行了详细的地质调查分析,在分析了降雨资料的基础上,利用变形监测资料,对受降雨影响下滑坡体稳定性进行分析,并分析降雨入渗时间、临界降雨量和降雨总量与滑坡体变形的关系,变形增量与降雨量的关系,其结果可以为选择滑坡治理措施提供依据,也为类似的滑坡地质灾害的治理积累经验。Prediction problem of large catastrophic landslide is an important applied research topic of geotechni- cal mechanics. Detailed geology survey and analysis for the Xiapuzi landslide were made; Based on the analysis of the rainfall data, analyzed landslide body stability under rainfall influence o Using deformation monitoring da- m,relationships were analyzed between rainfall infiltration time, critical rainfall and total rainfall, with the de- formation of landslide, and the relationship between deformation incremental with the rainfall. The results pro- vide a basis for choice of landslide treatment measures. The research accumulated experience for treatment of similar landslide geological disasters.
