Research On Safety Assessment Of Subway Shield Interval Crossing The City Business District

During the construction of the subway in major cities across the country,the phenomenon of subway crossing existing buildings has become more and more problems.For the crossing of existing railway projects,the construction is difficult and the design is difficult,and the new lines are generated for existing buildings.influences.This paper collects relevant information about the study of tunnels crossing existing buildings,and introduces the research status of passing through existing projects at home and abroad,and summarizes the main research contents at present,which is the safety assessment of the shield through the business district.reference.It is mainly for the Shijiazhuang Metro Line 6 to cross the Tianshan Business District for research.Due to the existing buildings,the structure is complicated and the surrounding buildings are dense.The construction may be on the existing and surrounding environment.Causes adverse effects.In view of the above problems,we should solve the existing building engineering research solutions and specific measures to ensure the safety of the structure,ensure the stability of deformation,and provide technology and experience for the same type of engineering.Using the finite element software,the finite element calculation is carried out.By obtaining the calculation results,the deformation characteristics of the structure are analyzed,and the reliability of the safety assessment can be ensured.In view of the complex environment surrounding the project,the environmental impact analysis of existing buildings was carried out.After the completion of the subway construction,the evaluation measures were carried out,and the damping measures used were analyzed to ensure that the environmental impact of the construction was minimized.
