  Research on a new device used to decrease excess pore water pressure of soil around shield tunnels

  Abstract: Grouting is important for shield tunneling as grouting material fills the adverse gap between segments and the surrounding soil. Generally, high grouting pressure will lead to large segment stress. In order to reduce the stress and deformation of segment, extra soil is usually removed behind the segment through a prefabricated hole located in the middle of each segment. However, this method may...
