| 摘 要： | 针对暴雨型滑坡灾害预报预警服务的需要,以江西为研究区域,建立了8个滑坡灾害监测点.通过监测试验,较系统地研究了大气降水对地下水位、孔隙水压力、滑坡土体应力及滑坡稳定性的影响;进行了大气降水、地下水位和滑坡稳定性的模拟,初步确定了江西省8个代表点促使滑坡复活的临界降水量指标,初步划分出江西省滑坡灾害预警降水量临界值.

| Abstract: | For meeting the service needs of predicting and warning landslides triggered by extremely heavy rainfall,by monitoring and experiment in eight trial grounds distributed in Jiangxi Province,the impacts of rainfall on underground water table,pore water pressure,soil stress and landslides body's stability are studied.Relationships among precipitation,underground water table and landslide body's stability are simulated.Critical index are calculated,which indicate landslide reliving.Threshold for predicting and warning Jiangxi trial ground landslides are divided. |
