Analytical and Numerical Study of the Support Pressure for the Stability of Shallow Underground Openings
Abstract: This paper describes the problem of assessing the stability conditions of shallow excavation of circular shape, namely circular sections of long cylindrical tunnels, in ground as it is modelled with a Mohr-Coulomb material. Firstly, the problem results in a closed-form statically admissible solution for cavities under the horizontal ground surface that allows an estimation of minimum support...

The Project Which Uses an Innovative Construction Method to Expand an Operating Subway Tunnel Built by the Caisson...
Abstract: This project involves renovating Minami-sunamachi station on the Tokyo Metro Tozai Line, by converting a single island platform with two tracks into two island platforms with three tracks to eliminate train delays and alleviate congestion during rush hours. Moreover, station facilities, escalator and elevator devices are also relocated to improve passenger flow. This Station was constructed by...
