Arch bridge grid beam hoisting displacement control method capable of eliminating temperature influence
The invention discloses an arch bridge grid beam hoisting displacement control method capable of eliminating temperature influence. Displacement control in the process is carried out by taking an archbridge with a suspender as an engineering object; a temperature correction factor is introduced, the displacement of the hoisting construction of the arch bridge grid beam is controlled,the influenceof the temperature on the displacement of the grid beam is eliminated,the minimum temperature influence of the hoisting grid beam is used as a target function,analysis is conductedby taking the displacement for controlling bridging closest to a reasonable bridging state as a constraint condition,the problem that the displacement of the grid beam is not easy to control due to the influence of temperature is well solved,the problems that the bridge floor is not smooth, the driving comfort is poor, the vehicle speed cannot meet the design requirement, and the traffic capacity is poor are solved,the arch bridge grid beam hoisting construction period is greatly shortened, the risk of forcibly selecting night construction is reduced, the economic cost is saved, wide application and popularization prospects are achieved, and huge economic benefits are brought.
本发明公开了一种消除温度影响的拱桥格子梁吊装位移控制方法。以具有吊杆的拱桥为工程对象进行过程中的位移控制，通过引入温度修正因子，对拱桥格子梁吊装施工的位移进行控制，从而达到消除温度对格子梁位移的影响，把吊装格子梁的温度影响最小作为目标函数，把控制成桥的位移最接近合理成桥状态作为约束条件进行分析，很好的解决了由于受温度的影响格子梁位移不易控制的难题，避免桥面不平顺、行车舒适性差、车速无法达到设计要求、通行能力差等问题，大大缩短拱桥格子梁吊装的工期，降低被迫选择夜间施工的风险，节约了经济成本，具有广阔的推广和运用前景，带来巨大的经济效益。
