Transverse partition method for reducing ground surface settlement and building structure deformation of underground structure construction
The invention discloses a transverse partition method for reducing ground surface settlement and building structure deformation of underground structure construction. In a foundation pit or a pilot tunnel, a transverse reinforcing structure layer which has controllable vertical bearing capacity and is located between an existing building foundation and a planned underground structure is formed through a non-excavation technology method. When the reinforcing structure layer is close to the bottom of the existing structure foundation, the reinforcing structure layer servers as a raft foundation or a strip foundation of the existing structure, and the capacity of the existing structure for resisting deformation is enhanced. When the reinforcing structure layer is close to the top of the planned underground structure, the reinforcing structure layer serves as a transverse bearing system of the planned underground structure, and influences of stratum deformation caused by the planned underground structure on the existing building foundation are isolated. The transverse partition method can effectively reduce the problems of ground surface settlement in the underground structure construction and deformation of adjacent buildings, and has the advantages of being good in construction flexibility, wide in application range and controllable in reinforcement effect.
