The construction of deep pit has a great impact on the surrounding environment, which is mainly reflected in the subsidence of surrounding soil. Because of the particularity in geological and hydrogeological conditions of riverside floodplain area, environmental impact assessment is needed. According to the monitoring data of practical engineering, the deep pit in the floodplain area near Yangtze River may cause a large subsidence of the surrounding soil with a rapid subsidence rate and a wide range of subsidence effects. The subsidence of the surrounding soil increases with the depth and time of excavation, and the post-construction subsidence effect is not obvious. The environmental effects of the deep foundation pit project in this project have provided valuable experience for guiding the implementation of the deep foundation pit near the floodplain in the future.
