Estimation Method of Falling Concrete Piece from Tunnel Lining

Last updated on 25 March 2013 1:04

This paper describes a method for quantitatively evaluating the falling of concrete pieces from tunnel linings, comparing the shear stress acting on crack surfaces with the shear capacity. The shear capacity of cracks of various width, inclination angle and roughness were investigated by double shear tests simulating the fall of...
