Abstract


With huge investments of state investment in high - speed transport undertakings , the continuous improvement of the road network planning , bring our transportation construction a climax , criss-crossing the highway is distributed in every corner of the motherland . Bridge structure as an indispensable part of the road traffic has also been an unprecedented development . Prestressed concrete continuous rigid frame bridge its Jointless smooth driving , no seat , convenient construction across ability , etc. , become a highway bridge span structure in the form of preferred . Continuous rigid frame bridge home and abroad , of the key technologies of continuous rigid frame bridge cantilever cast-in-place construction were analyzed . Prestressed concrete continuous rigid frame bridge construction control characteristics and requirements affect the the cantilever construction process in hanging basket bracket and folded analysis to ensure that the design of the bridge into a bridge linear and internal force requirements . Hanging basket under the most unfavorable load all the major load - bearing component force characteristics inspecting calculation of its scientific and rational optimization . Discussed the role of the various elements of continuous rigid frame bridge closed , the calculation method and its impact on the structure , the top thrust pushing displacement relationship , stiff skeleton set methods , prompting a full-bridge closed smoothly and successfully complete the actual project construction control . After the same type of bridge construction the construction control program can learn .
