With the implementation of strategies such as the "Golden Central Development Belt", Shanghai is once again experiencing a wave of development. With the large-scale construction of regional centers, the multiple foundation pits are often developed and constructed simultaneously on the multiple plots of land in a region. A large group of foundation pits needs to be completed in a relatively short period of time, and the continuous dewatering of foundation pit at different stages and degrees may have the adverse effects on the surrounding environment, especially under the unfavorable factors such as rail transit in the surrounding area. In order to reduce the impact of group pit dewatering on the surrounding environment, it is particularly important to coordinate and manage the group pit dewatering in the early integrated design and operation. Relying on the dewatering practice of the Jinding Area Group Pit Project in Shanghai, the concept of integrated design and operation management of dewatering is proposed to reduce the impact of decompression and dewatering on adjacent rail transit. Based on the specific implementation of on-site group pit dewatering and combined with the analysis on the deformation of surrounding rail transit during the implementation process, the experience of integrated design and operation management of group pit dewatering is summarized, which has achieved the good economic and social benefits.
