Analysis on the Influence of a Deep Excavation in Tianjin on Surrounding Environment

Abstract:

In this paper, which was based on a deep excavation project in Tianjin, the factors and laws of surrounding buildings and surface subsidence during the excavation were discussed through the real-time monitoring and comprehensive analysis of the subsidence of structures, underground pipelines, ground surface and some other items. The results show that the main influence scope of the excavation to surrounding areas is about 2 times the depth of the pit, and enhancing the stiffness of surrounding buildings can increase the resistant capacity against deformation, which will provide a reference for the allied projects.
