Differential displacement control of deep foundation pits in soft clay by use of top-down excavation method

Xiaohang Guo

Abstract

Based on the project practices of Shanghai Tower,the differential settlement control of deep foundation pits using top-down excavation method is introduced.As the data illustrate,the measures like estimating analysis,dynamic design,information-guided excavation are of great values in the differential displacement control,consequently they help ensure the safety of the project.
