Numerical Simulation Of Excavation And Support Wen Bo Square

With the increasing development of urban construction, the deformation characteristicsof deep excavation analysis and stability evaluation has become an important issue ingeotechnical engineering, research the numerical simulation and dynamic monitoring of deepfoundation support has important application value.Because the project is located in abuilding or roads criss-crossing dense area, so deep excavation is often limitedspace,Therefore,during excavation, the deformation and its impact on the surroundingenvironment becomes a problem during excavation construction need to focusattention.With increasing depth of the excavation, the existing theories have been unable tosolve new problems, in order to successfully conducted the project, the Government duringthe construction Deformation of Foundation Pit adverse impact on the ecological environmentmade more stringent requirements.Collect detailed information including project overview,,engineering geology andhydrogeology conditions of Zhengzhou Wen bo Square deep excavation,using the finiteelement calculation software simulated excavation and supporting.Combined with theconcrete practice of the deep foundation excavation and using the ABAQUS program tosimulate the displacement field (including retaining wall deformation, uplift the bottom of theexcavation, surface subsidence, deep soil around foundation displacement etc).According tothe displacement field variation, in-depth study of the causes of subsidence and displacementin the surrounding soil and supporting structures.The results prove that excavation structure issafe and reliable, in order to illustrate the numerical simulation of ABAQUS finite elementmethod based on reliability and practicality.
