Abstract:

 A test of three reinforced concrete (RC) lining segments of fullscale was carried out. The effect of the loading method and reinforcement ratio on the failure mechanism and ultimate bearing capacity of the RC lining segments was analyzed based on the test results. Test results indicated that the cracking load, the yielding load and the ultimate load obviously increases because of the  axial force effect. The yielding load and the ultimate load slightly increase with an increase of the reinforcement ratio, but the cracking load was hardly affected by the reinforcement ratio. Based on the analysis of the failure mode of lining segment, formulas for the bearing capacity of the lining segment to eccentric compression are proposed.
