Continuous Rigid Frame Bridge Control Theory And System Research

With prestressed concrete continuous rigid frame bridge applications morewidely, the span increases, more and more high pier height, design and constructionrisk is correspondingly increased, especially bridge construction and operation of thefrequent accidents occurred, in order to enhance the quality, safety management ofhighway bridge engineering, construction optimization program, to avoid accidentsprojects to improve construction safety, and in order to ensure the safety of rigidframe bridge construction, the construction process must, especially for the mainbeam suspension poured The whole process of construction monitoring, checking forstructural design of highway bridges and culverts in accordance with specifications,simulation analysis of the construction plan, make evaluation of their feasibility, andput forward reasonable proposals, stress, temperature, real-time monitoring of thegeometric structure of the state to provide security warning, adjust the value ofconstruction put forward to ensure the structural stress, linear meet the designrequirements.In the Hanjiang River Bridge as an example, through the establishment of thedeformation, stress monitoring system design, simulation of the bridge structure, andconstruction of structural cantilever casting distortion control, stress control structures,structural stability control, safety control structure, forming a complete monitoringmethods and monitoring techniques.
