The invention discloses a huge ultradeep foundation pit accurate subsidence and environmentally-friendly construction method, which belongs to the technical field of constructional engineering. In the design and construction process of a huge ultradeep foundation pit, the accurate prediction and control of the subsidence of the ground surrounding the foundation pit due to compression of a water-bearing stratum during the pumping of confined water in the pit are performed. In the invention, the operation is simple, a handling method is reasonably determined and selected when the subsidence is subsidence is predicted accurately, and thus, the subsidence of the surrounding ground is controlled, environment is protected and the method is an economic construction method.
Description
Precise Settlement and Environmental Protection Construction Method of Ultra-Large and Ultra-Deep Foundation Pit technical field The invention relates to a method in the technical field of construction engineering, in particular to a precise settlement and environmental protection construction method of a super-large and super-deep foundation pit. Background technique With the continuous economic growth in the Yangtze River Delta region, the pace of urban construction is also accelerating, and the ground space is far from meeting the needs of economic development in large cities, and more and more underground projects have emerged one after another. Therefore, foundation pit engineering has also become a new hot spot in the construction of coastal economically developed cities. More and more ultra-large and ultra-deep foundation pits appear in cities, and the excavation depths of various types of foundation pits have directly entered the corresponding confined aquifers. Th...
