EXPERIMENTAL STUDY OF MECHANICAL CHARACTERISTICS OF TUNNEL SUPPORT SYSTEM IN HARD CATACLASTIC ROCK WITH HIGH GEOSTRESS

Experimental Study of Mechanical Characteristics of Tunnel Support System in Hard Cataclastic Rock with High Geostress

In hard cataclastic surrounding rock with high geostress, the rock monomer strength is high and the rock is broken, and tunnel excavation in it is apt to cause large deformation, collapsing, and breaking, causing initial support crack and even intruding of the initial support deformation.The characteristics of the support system under different sup
