独塔空间索面自锚式悬索桥主缆线形分析

Analysis of Shape Finding of Single Tower Self-anchored Suspension Bridge with Spatial Cables

采用节线法计算理论和分段悬链线理论,分别计算了一座独塔空间索面自锚式悬桥梁主缆成桥线形坐标。结果表明了两种方法的可行性,能够满足工程计算精度要求,同时通过计算过程及结果对比分析,指出两种方法的优缺点。

With the division line method theory and catenary element calculation method theory,this paper calculated the completion status coordinate of main cable of self-anchored suspension bridge with single tower and special cable.It is suggested that these two methods are both feasible and can be satisfied with the accuracy in practical engineering,and two method can be used in the determination of completion status of self-anchored suspension bridge with special cables.At the meantime,both the advantages and disadvantages were pointed out by contrastive analysis.
