摘要
针对钢管混凝土拱桥的吊杆在既有内力的情况下进行优化控制,力求在最后一次张拉后使控制内力达到设计要求。问题的关键在于运用数值模拟分析出各吊杆张拉对其余吊杆的影响函数,通过对各函数的组合计算出最优的张拉方法。
In allusion to the optimizing control of steeves on concrete filled tubular arch bridge,it strives to make the internal force achieve the design requirement under the last tension.It is critical to use numerical simulation to analyze the influence function of stretching one steeve on the others and find out the optimal tensioning method by combining and calculating each function.
