Analysis on Surface Displacement Caused by Groundwater Seepage of Shield-Tunneling

Abstract:

Seepage is one of the unfavorable factors inducing construction accident. It is essential to analyze the influence to the displacement from seepage by the variety of the parameter of seepage. Set up simulation model by software Abaqus. This text studied the law on the displacement of groundwater during construction considering the influence of groundwater seepage, and contrasted the simulation data with groundwater and without groundwater. The pore water pressure changes because of the influence to seepage field from excavation. the displacement curves head for the same on different porosity. The settlement increase and the swell decrease with the addition of porosity. It is obvious that the displacement with groundwater is lager than without groundwater. A suggestion is made that the tunnel engineering should be designed with considering the influence of groundwater.
