摘　　要：本文以中国长江三峡工程库区大型滑坡——宝塔滑坡为例 ,在地质结构研究的基础上 ,尝试通过地下水动力场、水化学场、水温度场和水的环境同位素的调查研究 ,查清地下水补给、径流、排泄条件和地下水随外界因素 (降雨、水库蓄水和人为入渗、排水等 )变化的规律 ,从而建立滑坡地下水系统的概念模型。这既是滑坡的地下水预测和变形预测的必要基础 ,也为滑坡的治理指明了方向。In a case study of Baota landslide in the reservoir area of Three-Gorges project, a conceptual model for ground water systems in large-scale landslide was established by integrating the studies of groundwater dynamic field, physical-chemical characteristics, environmental isotopes, and temperature of ground water in the landslide. This model includes recharge, seepage, discharge conditions of ground water varying with the environmental factors (e.g. rainfall, reservoir impounding, and artificial surface water recharge, etc.). This is one of the keys to predict the slope stability and to take countermeasures to controlling landslide.
