| 摘 要： | 针对悬索桥锚跨索股的特点,介绍了索股几何长度迭代计算原理、索力计算模式、索股稳定性判据,并据此编制了FORTRAN数值计算程序,克服了以往悬索桥锚跨索股设计时曾采用的虚交点法导致计算索股与锚面的交点同设计有较大差异的问题；以某在建大型悬索桥为实例进行了锚跨索股分析,得出了相应结论.

| Abstract: | According to the characteristics of suspension bridge anchor span strand,the iterative calculation theory of the geometric length,cable force calculation model and the stability criterion of span strand were introduced;based on FORTRAN numerical calculation procedure,the significant difference between the designs of calculation cable strand and anchor intersection due to previous application of virtual intersection method when designing suspension bridge anchor span strand was overcome;based on a large suspension bridge under construction,a conclusion had been drawn. |
