三次元数値解析によるトンネル掘削工法の評価
About This Article
Descriptions
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.
