Stress-path and piezometric head field analysis of soil during earth pressure balanced shield tunneling

    Research output: Chapter in Book/Report/Conference proceedingConference contribution

    Abstract

    The effects of earth pressure balanced (EPB) tunneling on the soil stress path and piezometric head of the soil during tunnel advancement are considered in this study. First, the 3D stress distributions of the area near the crown and spring line of the tunnel are investigated, after which the tunnel stress path with respect to the Mohr-Coulomb yielding surface is presented. Next, by taking into account the three significant factors of a) advance rate of the tunnel face, b) consolidation coefficient of the soil, and c) overburden depth of the tunnel, a parametric study is conducted and the effect of EPB tunneling on the piezometric head field of the soil is examined.
