Description

technical field [0001] The invention relates to the technical field of deep foundation pit engineering, in particular to a method, device, terminal and storage medium for controlling decompression and dewatering in deep foundation pit engineering. Background technique [0002] With the continuous development of society, the requirements for underground engineering construction are becoming more and more complex, and the requirements for environmental protection are getting higher and higher. Most of the excavation construction of deep foundation pit projects requires decompression dewatering to prevent engineering accidents caused by pressurized water such as foundation pit surges and ensure construction safety. The confined aquifer has a huge impact on the foundation pit itself and the surrounding environment. Engineering accidents and surrounding environment damage caused by improper pressure reduction or failure of the confined water are one of the major risks of the foun...
