| Abstract: | Casting mass concrete of pile caps in long-span continuous rigid frame bridge is one of the key processes during bridge construction.The measures of crack control in mass concrete of cap influence the quality of the bridge and service period directly.Taking the 4# pier cap,right in Shuitu Jialing River Bridge as an example,the temperature control,construction technology and other issues are studied.Some effective engineering methods with the value of application are obtained. |
