| Abstract: | Currently in China,bowl buckle frame and beam-column frame in composite structural system come into construction of many cast-in-place concrete bridge.According to a composite stent construction instance of 2# bridge in Changbaishan International Tourism Resort,the stent design and specific technical measures in construction are introduced in this paper.Based on monitoring data of stent pre-loading,before pouring concrete stent adjustment program is achieved,and the precise elevation of framework legislation for arch bottom is determined,which provides a reliable guarantee for engineering quality and construction security. |
