Abstract:The analysis using the finite element method was conducted to model the construction of the jet grout slab which has effect on underground retaining walls and nearby soils in the deep foundation pit excavation of underground retaining wall. The calculated results and the factual results are also compared. The results show that the method could decrease the deformation of underground retaining wall and increase the stabilization of foundation pit excavation in combination of underground retaining walls and jet grouting.
