| Abstract: | Large-volume concrete is easy to crack during construction owing to the large difference between inside and outside temperatures of it. The crack of concrete was prevented effectively by taking corresponding measures during construction of the trestle of Xuejiaba Fujiang Bridge on Suiyu Railway Line with large-volume concrete based on the measured result of inside and outside temperature of the concrete. |

| Keywords: | bridge trestle concrete temperature control anti-cracking |
