Evaluation of active earth pressure on the facing of the shield entrance in a shaft
Abstract
This paper aims to establish a more reasonable method of estimating the active earth pressure at the shield entrance. Model experiments using dry sand were performed, and the observed active earth pressure was found to be much smaller than the value which was estimated by the existing design code. In order to simulate the experimental results numerically, analyses based on the 2D and 3D elasto-plastic FEM have been performed. It has been found that the analytical and experimental results agree well with each other.
