摘要
将最优化计算理论引入到拱桥拱肋吊装计算中 ,采用一阶分析法来确定拱桥的合理施工状态 ,求出各施工阶段的扣索索力和拱肋吊装高度 ,模拟了钢管拱肋的拼装过程 ,有效地解决了千斤顶斜拉扣挂体系调索次数与方法限制的难题。
The paper introduces the optimization theory and method into the calculation of erecting arch ribs, cables force and prearrangement height are obtained and the installation process of arch ribs is simulated by using first order optimization method to determine the rational construction stage. The limit of times and method of adjusting cables force using suspending and connecting system is effectively solved.
