Measurement and Simulation Study on Ground Subsidence Induced by Shield Tunneling in Sandy Stratum
This paper presents a study of the ground subsidence law caused by tunnel excavation with EPB shield machine, in which a Metro site was selected for data collection. With the data measured in field and tools of general FEM program ABAQUS, three-dimensional finite element model was established and a simulation study was conducted to analyze the construction progress under influences of all possible factors. Major regional and sub-regional factors influencing the ground subsidence were estimated, and the terrain types affecting vertical surface during construction and the amount of ground subsidence in various stages of construction are analyzed. Based on comprehensive understanding of these influencing factors, the prediction model for estimating ground deformation was studied. With the actual values of stratum and construction parameters as well as other relevant data for samples, the established model was applied to forecast the ground deformation and verification the availability and satisfactory results were produced.
