摘要
利用悬链线和抛物线理论分别建立架空缆索线型方程,推导两支承点不等高时两种曲线最大垂度,并建立张力方程,对比分析两种模型在架空缆索张力计算中的精度,以及采用抛物线理论计算架空缆索可接受的垂跨比范围,并得出一些有益的结论。
This thesis respectively establishes suspension cable linear equation with catenary and parabolic theories induces the largest sag of two curves under different height of two bearing points,and sets up tension equation.And then,it compares and analyzes the accuracy of two models in tension calculation of suspension cable and the sag ratio of suspension cable calculated with parabolic theory,and obtains some useful conclusions.
