| 摘 要： | 利用缆索静力平衡原理,建立了主缆按双吊点位置的分段曲线方程,推导了相应的主缆垂度和水平张力计算公式,分析了主缆双吊点距离、主缆跨径、主缆自重及吊重等参数对水平张力的影响。结果表明:影响主缆水平张力的主要因素是两吊点间距与主缆跨径之比,当两者之比在0.05以内时,用单吊点法和双吊点法计算结果差异很小,可忽略不计。

| Abstract: | Based on the principle of static equilibrium of cable,segmental curve equations of main cable with double-lifts in single span were established;formulae of the sag and horizontal tension were obtained;the influence of distance of double-lifts,span,self-weight,load and the like on horizontal tension was analyzed.Results indicated that the ratio of distance of double-lifts and span of main cable played an important role in affecting horizontal tension of the cable;the tolerance by the method of double-lifts a... |
