Research and Application of Special Underpinning System in Urban Underground Space Development
For the building displacement project in the development of underground space in the core area of the city,the design of the underpinning system for the cultural relics body and the basement roof when it is moved back will be mainly considered in the design stage.As a municipal cultural relic protection unit,Wuhan Baoshou Bridge adopts the protection scheme of moving out and then moving back.It has gone through multiple displacement conditions,such as 6.5m super-high lifting up,SPMT trailer moving out of the foundation excavation and SPMT trailer moving back to the basement roof.This paper studies and applies the special underpinning system in the development of underground space of Baoshou Bridge project,including super-wide cultural relics body underpinning,super-high overhead displacement underpinning and basement roof underpinning.It mainly introduces the underpinning technology,design and construction points,and actual results.
