Title: The Influence of New Foundation Excavation on the Existing Subway Stations and Its Countermeasures
Abstract:Research purposes:A new foundation excavation is located in the safety protection zone of existing subway,the distance between them is about 2.0m,the influence during the process of the new foundation...Research purposes:A new foundation excavation is located in the safety protection zone of existing subway,the distance between them is about 2.0m,the influence during the process of the new foundation excavation on the subway structure is inevitable.For estimating the influence,a FEM model is built to compute the influence of the new foundation excavation on the existing subway station through the FEM software ANSYS,furthermore the targeted counter measures is adopted.Research conclusions:(1) The influence of the new foundation excavation on the subway structure is significant,especially during the process of the foundation excavation and rainfall.(2) The influence on the subway station is largest when the foundation excavation is excavated to the bottom,the vertical displacement is 26.3 mm,and the horizontal displacement is 17.8 mm.(3) During the excavating,process the measures must be taken to reduce the influence to make sure that the subway station is safe.(4) The conclusions can be used in the similar project.Read More
