Abstract

According to the field measured data of a deep foundation pit of subway station of Ningbo rail transit, the paper studies the varieties of deformation rate and cumulative deformation along with excavation time, and estimates the proportion of deformation under different construction phases based on 450 monitoring data of 4 deep foundation pits. The result shows that the main deformation of diaphragm wall due to deep foundation pit of subway station in Ningbo soft soil happens in the third and the forth phases, and these two conditions should be the key point of hierarchical control.
