摘　　要：长江中下游降水丰沛,丘陵山区地下水位变化剧烈,地下水流场的变化会给地质灾害治理工程带来很大影响。将军山滑坡不断发展、规模不断扩大的直接诱发原因是地下水流场的变化,地下水作为核心因素直接主导了滑坡体的演化进程。文章对区内形成滑坡的主要地质环境条件进行了分析,重点探析了治理过程中地下水变化对灾害点的影响。大气降水的高强度入渗、上层滞水(“水膜”)的存在和发展壮大、地下水压力的增高3个因素导致了治理工程的失效。The middle and lower reaches of the Yangtze River have abundant precipitation,and the groundwater level in hilly and mountainous areas changes dramatically.The changes in the groundwater flow field have a significant impact on geological disaster control projects.The direct cause of the continuous development and expansion of the Jiangjunshan landslide is the change in groundwater flow field.Groundwater,as the core factor,directly dominates the evolution process of the landslide body.This article analyzes the main geological environmental conditions that contribute to the formation of landslides in the area,with a focus on exploring the impact of groundwater changes on disaster sites during the remediation process.The high-intensity infiltration of atmospheric precipitation,the existence and development of"water film",and the increase in groundwater pressure have led to the failure of the treatment project.
