摘要
以某连续梁拱桥为工程背景,利用影响矩阵法,求出吊杆二次张拉调值向量,对二次张拉施工过程进行优化。提出的优化方案经过Midas软件模拟计算,证明该优化方案简单有效。分析成果可为今后系杆拱桥吊杆二次张拉施工控制方面提供参考。
Taking a continuous beam steel arch bridge as an engineering example to get the optimized seconda-ry suspender-adjustment of work programme by using the influence matrix of suspender ’ s internal force. Through the Midas software simulation calculation of the proposed optimization scheme, it proves that the opti-mization scheme is simple and effective. The conclusion of this paper can provide secondary suspender-adjust-ment for the construction practice of continuous beam steel arch bridge.
