Abstract
During the construction of the urban subway,it is often the case that the subway tunnel passes under buildings.To study the impact of such subway tunnel on buildings,this article,based on a subway tunnel project,uses the method of numerical simulation to analyze the settlement of basement floor and pile caps and pile foundation deformation on account of the shielding tunneling before and after the grouting reinforcement.According to the analysis,grouting reinforcement and other measures should be taken during excavation to control the deformation indexes and reduce the impact of shield excavation on the buildings.关键词
