Security Measures Of Buildings Of The Subway Passthrough The Buildings

Since entering the new century, our country has entered a period of rapid development, urbanization process is accelerating.With the expansion of city scale,the urban population surge and the social resources concentrated overly.At the same time, due to the limit of the city ground space, it causes a series of city traffic problems.In order to ease the traffic pressure on the ground, the urban subway construction has been an inevitable trend.But because of the excessive concentration of the city buildings, the underground tunnel passes through the buildings inevitably when we begin subway construction, thus it causes adverse effects to the buildings easily.In order to guarantee the safety of subway construction and the use of buildings,many scholars and experts have done a lot of relevant research at home and abroad and they have achieved Some significant results.Based on the zhongshan road of the subway construction in nanchang city as the background, this paper researchs the Security measures of the buildings when the underground tunnel passes through the buildings.The main contents are as follows:1.This paper introduces the background and significance of the research of this topic.Based on the summary of the relevant results at home and abroad, it makes the analysis of the current research status.At the same time, this paper described the main contents and methods of the research.2.It introduces the theory and process of shield excavation and analyzes the theory of soil deformation caused by the shield construction.Based on the basis of theoretical analysis and practical experience, it puts forward the corresponding control measures to prevent the soil deformation.3.Through the study of the relevant specification, this paper introduces the evaluation standard of buildings deformation caused by shield construction.At the same time, it analyzes the theory of buildings deformation caused by the shield construction and puts forward the control measures to diminish the adverse impact.4.Depending on the actual project and the data, it detects and identifies the structure of buildings.Then, by using the finite element software SAP2000 simulate the effects of buildings caused by shield construction, it builds 3D model to analyze the stress and displacement.According to the results of analysis, it puts forward the corresponding risk identification and reinforcement measures.Finally, it puts forward the monitoring scheme and introduces the arrangement of monitoring points.
