Method of Calculating Surface Settlement at the Edge of Excavation Pit

Aiguo Yao

Abstract

Based on the former research on the excavation pit's deformation, the author provides a formula calculating the surface settlement caused by the deformation of supporting structure. And this formula is formed on the basis of normal distribution and triangular distribution. In addition, the surface settlement caused by the descent of water level is analyzed. This method can estimate the settlement at the edge of the excavation pit during the process of excavating and dewatering, and can provide more reasonable design scheme for the project.
