Time and Spatial Variations of Ground Subsidence Induced by a Shaft Excavation

Wang Wen-bi

Abstract

The self-correlated coefficient of time and spatial variations of the ground surface subsidence induced by a shaft excavation is studied in this paper.It is concluded that the time series have non-stationary property,in other words,the subsidence of ground surface has a deterministic trend.For the ground subsidence induced by a shaft excavation,time and space are two independent variables,and the ground subsidence is a function of time and space.It is possible to predict the ground subsidence during the construction.
