摘要
以三峡二期下游围堰基坑限制性抽水期间的大量观测数据为依据，分析了围堰堰体和防渗墙在土压和水压等作用下的受力和变形情况，指导基坑有计划地进行抽水，为工程安全提供必要的信息。
Vast amount of observation data obtained during the foundation pit limiting pumping for the stage 2 downstream cofferdam of the Three Gorges Project were used for analyzing stress and deformation of the cofferdam body and impervious wall under earth pressure and water pressure to direct pumping from the foundation pit in a planned way. This provided necessary information for the safety of the project.
