Research Situation of Large Deformation Mechanism and Prevention-Control Measures of Surrounding Rock in Tunnel

Abstract:

The tunnel and the understructure works are excavated in the rock or the soil. In comparison with surface engineering, design construction and maintenance of understructure works are more complicated. Especially, after the underground rock or soil is excavated, the large deformation which generated by the crustal stress field change, will bring the great difficulty for supports and protections of surrounding rock. Based on this fact, this paper introduces the current research of formation mechanism of surrounding-rock large distortion that was met in the construction and operation of the tunnel and understructure works, and the prevention measure that was adopted at home and abroad currently. New knowledge is acquired through study; this will draw very useful reference to deeply-buried long tunnel construction in the future.
