Numerical study on rock failure around a tunnel destressed by a conceptualized notched technique
A destressing method for reducing the strainburst risk in burst-prone grounds is suggested. In this method, the rock is destressed by cutting notches at the excavation boundary. First, the concept of the proposed method is described both analytically and numerically. Then, the method is applied to a...
