    • Abstract
  • It is the first time to use EPB method in the subway construction in Xi’an loess strata. There is no better work experience for reference. The difference between the observed results and the Peck expressions is larger for the ground settlement trough. The real process of shield tunneling construction is simulated by FEM with Duncan-Chang model, which is programmed with APDL. The Duncan-Chang parameters, moisture content and depth of the tunnel axis are employed to perform quantitative analysis. The law of the ground settlement induced by subway construction with shield tunneling in Xi’an loess strata is studied, and an expressions is put forward to predict a certain measured ground settlement. It shows that the expression is suitable for the investigation of the ground settlement characteristics, and the conclusion is significant for similar projects with shield tunneling in Xi’an loess strata.
