Abstract
A comprehensive study of the structural integrity of a precast concrete tunnel was conducted following the discovery of cracking, during construction, in some sections of the tunnel liner. The structural behavior of the jointed tunnel ring was investigated through experimental testing and computer simulation. Data gathered from field performance monitoring and full-scale laboratory testing was used in conjunction with numerical simulation to investigate the effect of stress concentrations at bolt pocket recesses and excessive rotation at jointed connections.
