Abstract

Semi-shallow water soft soil foundation pit usually have unbalanced earth pressure and soil strength is low. Therefore its support is more difficult in this situation. Anchor-grouting tube technology in geotechnical engineering as a new type of grouting technique has been widely applied in the engineering, this paper applies the technology of soft soil foundation pit supporting, and expounds the concrete application form, whether through site for the application of anchor tube process of soft soil foundation pit respectively for steel sheet pile lateral displacement monitoring, and based on the finite difference method for foundation pit deformation and sliding field is studied. The calculation results show that the technology can effectively control the deformation of foundation pit in soft soil, especially for deformation control.
