Importance of face pressure and tail void grouting on numerical modeling of shield TBM tunneling through soft ground...
Abstract: Shield tunneling is now becoming a general trend in tunnel excavation. Despite the growing importance of shield tunneling, a prevalent standard for its numerical analysis has not been established yet, due to difficulty in appropriate implementation of face pressure, tail void grouting, and continuous excavation steps during shield TBM tunneling. Since there are various empirical methods to...

Laboratory Study on Characteristics of Foam - Conditioned Weathered Granite Soil
Abstract: The weathered granite soil that is widely distributed in the Korean peninsula has unique characteristics compared to typical sandy or clayey soils. When tunnelling the ground consisting of the weathered granite soil by the earth pressure balance (EPB) shields, it is necessary to evaluate the effect of foam conditioning on the behavior of the weathered granite soil. In this study, a...
