squeezing rock tunnel bench cut excavation advancing drift support effect field measurement

Generally, the bench cut excavation is adopted in squeezing rock. However, advancing drift is used as auxiliary method for the occurrence of large-scale earth pressure in Nikkureyama Tunnel II . This paper is tidying field measurement data of Nikkureyama tunnel II. It is examining the effect of bench cut and advancing drift by using 3D-FDM. Also, it is proposing optimum bench length and drift length from the above result.
