Abstract：
Changning Raffles City is located at the central district of Shanghai and on a fluid plastic silty clay stratum surrounded by complex conditions. The foundation pit is deep and there were many pits at the bottom of foundation pit. High-pressure rotary spray construction technique was adopted to strengthen the bottom of the foundation pit to effectively control the enclosure structure deformation and bottom soil upheaval and guarantee the safety of surrounding building and foundation pit construction.
