Prediction of antecedence displacament using Convergence-Confinement Method

Abstract

We confirmed the prediction of surface settlement with Convergence Confinement Method. It is difficult to measure the antecedence settlement of convergence and crown settlement, which are used as a control point in tunnel excavation. In this investigation, we confirmed the prediction of displacement curve which do not measure antecedence settlement with Convergence Confinement Method.
