摘　　要：由于普速铁路存在多曲线且曲线半径较小的线路段,对此部分线路的接触网锚段长度及中心锚结位置确定需进行精确的计算。本文基于吊弦与定位器偏移引起接触线张力差计算,研究了中心锚结处张力差计算与锚段长度的确定方法,得出了多曲线线路上中心锚结处的张力差需分段计算后迭代考虑并最终确定锚段长度的结论。Due to there are line sections with multiple curves and the line sections with minor curve radii,therefore,accurate calculation is required for determination of length of overlap section and mid-point anchor for OCS of these sections of the line.The paper,on the basis of the calculation of tension difference of contact wire caused by displacement of droppers and steady arms,studies the methods for calculation of tension difference of mid-point anchor and determination of length of overlap section,the conclusions are obtained that the tension difference at place of mid-point anchor above the line with multiple curves shall be calculated section by section,considered iteratively and the length of overlap section then be determined finally.
