The computer application program that is applied based on the finite difference method. By taking the soil nailing support structure in Shijiazhuang city as an example, the three-dimensional computer numerical model of deep foundation pit is set up; the horizontal displacement and the ground settlement of the deep foundation pit are simulated in the process of excavation and support. The simulation result is consistent with the test result. The results show that the deformation behaviour of the deep foundation pit can be analysed by using three-dimensional computer simulation technology in actual project. The method overcomes the deficiency of theoretical analysis method and offers effective guidance for design and construction of foundation pit excavation and support.
