The Safety Analysis Of Wu Qiaoling Tunnel F₇ Fault Supports And Protections Structure

This article develops in the generalized analysis current soft cragbig distortion tunnel in foundation, Depends on Wu Qiaoling the F7 fault tunneling background, Gauges and applies computation methods and so on the finite difference method and large-scale general finite element software ANSYS through the scene construction monitoring, fault tunnel has carried on the initial period supports and protections and two lining work structure safety performance analysis and the research to Wu Qiaoling the F7, has drawn some beneficial conclusions and the suggestion.The paper mainly has three aspects to compose: Scene construction monitoring gauging and data acquisition; Three dimensional and two-dimensional value computation analysis; To two lining work crack secure appraisal.Tests the part through the scene the embedment and correlation data gathering, then obtained the first primitive monitor data, and through to the test data regression analysis, obtains the correlation regression curve.Uses computation methods and so on the finite difference method and large-scale general finite element software ANSYS, separately has carried on three dimensional and the two-dimensional value computation analysis to the tunnel initial period supports and protections and two lining works, thus appraisal tunnel initial period supports and protections and two lining work security.Used large-scale general finite element software ANSYS to carry on the plane analog computation analysis to two lining work cracks, indicated and elaborated the crack appeared the reason, and proposed the related project reinforcement measure.The present paper through the scene monitoring gauging and the value computation analysis, fault soft crag big distortion tunnel has conducted the related research and the analysis to Wu Qiaoling the F7, therefore this article will have certain reference guiding sense to the next similar tunneling design and the...
