Key Technology For Tower And Beam Synchronous Construction Of PI Wang Road Cable-stayed Bridge

PI Wang road cable-stayed bridge because construction time limits the tower and beamconstruction method. Combined with the actual project PI Wang road cable stayed bridge,to the other beam synchronous construction method and control technology research anddiscussion, the main contents are as follows:(1) Describes the tower construction method, its advantages and disadvantages;determine that Taria synchronous construction error is the main factor to influence;development of the PI Wang road tower synchronous control measures for theconstruction for each main influencing factor.(2) Combinations with the road cable stayed bridge engineering concretecircumstance, identifies the point road cable stayed bridge construction steps anddifferent parts of the construction scheme; construction control principle and theestablishment of quality, schedule and safety measures.(3) Using the finite element method, establish the PI Wang road cable stayed bridgefinite element analysis model; based on the first beam construction method of tower andtower and beam construction method, the construction process simulation; comparisonbased on two kinds of construction methods of bridge deformation and stress conditions,further verifies the tower and beam construction method feasibility; and analysis of thepartial load on the stress and deformation of bridge impact.The research in this paper has a vale reference value on the construction of thesimilar bridges.
