| Abstract: | Crack limit values home and abroad are analyzed and compared,and then the connotation and characteristics of the allowance width of crack are pointed out respectively.It is proposed that durability crack limit should take environment,steel,stress characteristic,component styles,crack position and construction feature into consideration.The crack limit range and relationships of concrete component and pre-stressed concrete component are concluded in alternate drying-wetting,no alternate drying-wetting and corrosion environment,which provides useful reference for allowance width of crack in concrete bridge constructor based on durability. |

| Keywords: | concrete bridge durability allowance width of crack environmental effect |
