The Construction Monitoring And Controlling Cable-stayed Bridge With Inclined And Arched Tower

Cable-stayed bridge is an indeterminate number of relatively high structural system, currently in bridge construction has a relatively wide range of applications. No backstay cable-stayed bridge is a rather special. Bridge construction is more complicated, the main beam in the construction process of casting, welding installation of the tower arch, especially the tension cables are to be calculated analysis and on-site monitoring, real-time tracking. In this paper, the South Third Ring Road Bridge in Datong as engineering background, set up a finite element model, and a construction process simulation. Focus on the positioning arch tower installation, tensioning cables and the tower arch concrete casting was simulated, and the construction process control.Bridge on the South Third Ring Road in the structural interpretation and understanding of construction methods, the development of a detailed construction monitoring program, mainly to monitor the contents of the South Third Ring Road bridge, monitoring the project, monitoring sites and monitoring methods. In this paper, utilize MIDAS CIVIL professional software to build a bridge structure finite element model of the bridge, and the actual construction process of the construction phase. Focus on the process of tensioning cables and the tower arch concrete pouring sequence was simulated, and the tension cables and concrete placement scheme was optimized. Control throughout the construction process of the monitoring data were analyzed, especially for some of the key conditions of the data were analyzed and identified.In this paper, Datong Bridge, the engineering background of the South Third Ring Road, on the whole construction process was monitored and controlled. It has some meaning to Monitoring and construction of the cable-stayed bridge.
