碩士 === 國立中興大學 === 土木工程學系所 === 96 === The methods of precast launching or on-site casting are mostly used for the construction of bidges in Taiwan. The paper has collected the construction methods commonly used and briefly introduced their construction steps, appropriate range, construction flowchart, advantages, disadvantages and equipments. The paper selects the “cast-in-place cantilever construction prestress bridges”method as research topic. This paper addressed the problems that could be easily happened during the construction and offered the solutions to them. In addition, the paper also provided a check-list for the workers on sites to prevent from failures. Finally, the paper derived the failure loads of the bridge due to the actions of moment and shear respectively. The ratio of the flange area to the web area which could lead the moment failure and shear failure to occur at the same time was also derived.
