Abstract
Study of grouting reinforcement to disturbance soft soil caused by large diameter slurry shield construction based on Jiangyin Chengjiang West Road over the river tunnel project. First, Three-dimensional finite element model is created to use the ABAQUS finite element software, considering nonlinear deformation of soil in the numerical calculations. By numerical simulation: horizontal, vertical, vertical displacement trends are in accordance with the measured data; increase the layer E, C, φ values can effectively reduce the settlement of soft soil layer, reducing the soil disturbance. Therefore, through grouting reinforcement of upper soil can reduce soil settlement and get to the purpose of reducing the soil disturbance.
