Deep Foudation Pit Reinforcement Effect And Utility Research Under The Condition Of Muddy Land

In the Pearl River Delta region,the soft soil have some special characteristics.Such ashigh moisture content, Loaded deformation, low bearing capacity and space-time effects. Forthe civil-engineer, how to deal with the construction of soft soil foundation deformationencountered during the majority of to become a common problem encountered.Beause thePearl River Delta region of Quaternary soft soil is recently deposited soil, most of the softsoil are normally consolidated soil or owe consolidated soil, the soil structure is soft, theexcavation inside the passive role of embedded solid area of support structure contribution islimited, there is a big difference between passive earth pressure calculation model can providesoil pressure and commonly used design software provided to enhance the security andstability of the structure of the excavation, in the actual construction process, often throughthe passive region reinforcement to improve the conditions of passive earth pressure zone,but in the actual project, such as the rationale for deep excavation and other commongeotechnical design software for the reinforcing effect pit area inside the passive aspect of thejudgment there are some flaws and shortcomings, designers were on the right pit passivereinforcement design area causing distress.This article from the pearl river delta region of soft soil and the microstructure andmechanical properties of soft soil, based on the pearl river delta region soft soil passive earthpressure calculation theory and passive area soil consolidation method, theory study, bymeans of numerical analysis method for passive area soil mass in foundation pit engineering,the reinforcement method, comparing the change of different reinforcement factor of passivezone of foundation pit supporting structure deformation and earth pressure of soil, theinfluence of the pearl river delta region of deep soft soil reinforcement theory for further study,and with the aid of finite element analysis software Midas GTS geotechnical, through theanalysis of nansha Toyota north pit model. This article main research work, the pearl riverdelta was analyzed and discussed in foundation pit engineering in passive zone distributioncharacteristics of soil pressure, and using pit reinforcement, plus solid depth, width, and thearrangement of the solid form factors such as the displacement of retaining structure forfoundation pit and surrounding soil displacement, the influence of the passive area soil stressetc, trying to get more valuable research results, for the future engineering practice pitreinforcement scheme to provide the reference.
