Measurement and Simulation of Ground Deformation Due to Pneumatic Caisson Construction

摘要

Combined with one shaft construction employing pneumatic caisson in Shanghai, in-situ measurement of ground deformation was conducted. Based on the particular construction process of pneumatic caisson, one kinematic numerical analysis method was proposed for evaluating its influence on the surrounding strata. Through comparisons between calculated results and measurements, the proposed mechanical model and numerical analysis method were verified.
