Numerical Simulation Analysis of Soil Nailing Wall Based on FLAC during the Excavation of the Foundation Pit
On the basis of a typical engineering, a foundation of soil nailing walls supporting simulation model of soil nailing on the structure of the excavation is established with FLAC, the construction process of the supporting structure is analyzed in the dynamic simulation. The deformation characteristics of the supporting structure are analyzed during the construction process, the law of the supporting body deformation with the difference of excavation steps is summarized. The situ test data of the deep foundation horizontal displacement and vertical displacement are obtained by testing in situ. Some useful conclusions are summarized by comparative analyzing the numerical simulation value and situ test data, providing guidance for the design and construction of the pit soil nailing wall.
