Numerical Simulation Analysis And Support Deep Foundation Pit Of Subway Station

With the development of cities and urban rail transit engineering, more and moresubway stations were built in areas with heavy traffic and underground pipelinecomplex urban downtown areas. Cover and excavation top town method has becomean effective approach adopted by busy city centre Metro station construction at homeand abroad for its advantages of convenient construction, short duration, low cost andless interference characteristics.City subway station deep foundation pit supporting, this paper cover theconstruction example of inverse approach, according to the geological conditions ofthe project, the use of reason is deep foundation pit F-SPW software analyzes theload cases of10displacement of retaining structure deformation and surfacesubsidence, and on the overall stability of foundation pit supporting, verified theproject selection of supporting design scheme is reasonable.In this paper, at the same time using large-scale finite element analysis ofgeotechnical engineering software Midas GTS10conditions for the finite elementnumerical simulation, summed up the level of the soil under the condition ofexcavation process occurs, even the wall deformation characteristics, the results andthe principle is deep foundation pit F-SPW comparing the calculation results, thetwo calculation results is good, to illustrate the parameter selection of the model isrelatively reasonable, simulated to provide the reference for future researchers.Obtained through the analysis of the above two methods, the engineeringgeological conditions, the excavation and supporting the construction of theunderground continuous wall under the condition of horizontal displacement of thechange, and so on and so forth, for the future design and construction of similarprojects provide a reference basis, has the practical significance.
