STUDY ON ROCKBURSTS AT THE FACE OF A DEEP TUNNEL, THE KAN- ETSU TUNNEL IN JAPAN BEING AN EXAMPLE

In the Kan-etsu tunnel, which is one of the deepest expressway tunnels in Japan, rockbursts occurred mostly at the tunnel face. In order to prevent them, the authors carried out several investigations, including the measurements of initial rock stresses and the change of rock stress ahead of the advancing face. It was found that the areas of the core disking, observed at the coreboring before the excavation, fairly corresponded to those of rockbursts. Through these investigations and observations, the mechanism of rockbursts at the tunnel face is discussed. The number of the covering abstract of congress is TRIS no. 385148. (Author/TRRL)
