Constructional Controlling

Constructional controlling-technology plays a very important role in bridge construction technique and quality control. For the sake of increase of bridge spans, the constructional control of continuous rigid frame bridge is becoming more and more concerned, and has become the hotspot in the engineering construction area. This thesis discusses its history and current situation of domestic and foreign bridges at first, and its assignment and common method are summarized, and then the source of construction control errors and influence factor are analyzed. Based on the theory above, the constructional control strategy is proposed with feedback control method for the 3rd FUJIANG Bridge, and then correlation data at every construction stage is gathered to analyze the rationality of this constructional control strategy. Constructional control efficiency of this bridge is also analyzed, and the load-test has been conducted on this bridge after completion. Results show that the constructional control strategy for the 3rd FUJIANG Bridge is correct, reliable and consummate. This strategy is applicable to such bridges that have similar constructional characteristics.
