摘要

Through an elastic-plastic analyse of FLAC3D program which based on the explicit difference method,and from the case of urban complex of the third space deep excavation project in Tangshan on composite soil nailing combined with general soil nail and prestressed anchor.Numerical simulation is carried out the horizontal displacement on the top of pit foundation,which with measured date is discussed.The analysis shows that the composite soil nailing can largely restrain the pit foundation deformation. The successful application supplies some reference to similar projects in future.
