针对悬索桥主缆架设时锚跨张力的控制问题,基于现场施工存在临时固结措施的实际情况,提出了对摇轴式散索鞍按张力相等为条件的计算方法;并对锚跨张力分施工阶段与成桥阶段进行两阶段调控,对应满足不同阶段的索力控制要求,以使成桥后线形、内力都达到设计目标。

According to the control problems of the cable tension of anchorage in the erection of the main cable of the suspension bridge,the paper,based on the fact of the temporary consolidation measures in field construction,points out the calculation method for the rockshaft splay saddle by taking the equal tension as the condition,undertakes the adjustment and control at the two stages of the tension of anchorage,that is,the construction and complete stages,and illustrates the respective requirement of the cable tension control at various stages,so as to achieve the design purpose of the linear and internal force after the complete of the bridge.
