| 摘 要： | 主缆的架设精度(或架设质量)在很大程度上取决于基准索股的架设精度,而基准索股的架设精度主要取决于架设条件下(一般为非基准状态)基准索股架设垂度修正量的确定和达到修正垂度的控制方法。介绍基于抛物线理论和基于悬链线理论的平胜大桥基准索股非基准状态下架设垂度修正量的确定方法及达到该垂度的施工控制方法。

| Abstract: | The precision (or quality) of main cable erection depends to a great extent on that of datum strand erection while the precision of the datum strand erection in turn mainly depends on the determination method of sag modified quantity of the datum strand under condi- tion of erection (usually a condition of non-datum state) and the construction control method for the strand when it is just to meet the modified sag.In this paper,two kinds of the aforesaid methods based on the parabola and catenary theories for the datum strand erection of the self-an- chored suspension bridge of Pingsheng Bridge in Foshan under non-datum state condition of erec- tion are presented. |
