This book introduces the synergy theory model to analyze the calculation results of the soil deformation and the lateral displacement law caused by the longitudinal shield tunneling based on in-depth scientific research and engineering practice on deformation of structures caused by shield tunneling. The influence of shield tunneling on different adjacent foundation buildings was studied, and the deformation law and internal force distribution law of the structures were obtained. It aims to help practitioners in understanding the mechanism, predictive analysis method, and corresponding control technology of the influence of surrounding structures’ deformation caused by shield tunneling.
