浅谈跨国道现浇箱梁施工安全保证措施

The Safety Assurance Measures for the Construction of Cast-in-place Box Girder in the International Highway

以广东省开春高速锦江特大桥(35+55+35)m连续刚构箱梁上跨G325国道为工程背景,为保证跨国道现浇箱梁施工中满足施工工期及安全等要求,结合工程实际情况,对变截面现浇箱梁跨G325国道安全保证措施进行相关分析。

In this paper,the continuous rigid frame box girder of Jinjiang Super Large Bridge(35+55+35 m)on Kaichun Expressway in Guangdong Province spanning G 325 national highway is taken as the engineering background.In order to ensure that the construction period and safety requirements of cast-in-place box girder on cross-border highway are met,the safety assurance measures of variable cross-section cast-in-place box girder spanning G 325 national highway are analyzed in combination with the actual situation of the project.
