| 摘 要： | 钢管混凝土拱桥拱桁架节段安装常采用无支架缆索吊装斜拉扣挂法，计算的扣索控制索力值关系到节段标高控制和扣索数的确定，本文在总结现有斜拉扣挂法施工的基础上，提出定长扣索施工法，大大缩短了拱桁架节段安装过程，其关键在于控制索力的计算。

| Abstract: | The segments of the CFST arch bridge are often erected using the cable way method, in which the segmental elevation and number of cables are determined with calculated forces in control cables. Based on the existing method, a one time jacking cable method is proposed in this paper, which could significantly shorten the construction time. It is indicated that, in the improved method, the key procedure is the calculation of forces in control cable. |
