摘　　要：次档距线长积分法基于斜抛物线理论通过积分求解次档距线长,应用次档距线长积分法和次档距线长余量均分法分别计算同一算例的次档距线长,结果表明:高差系数绝对值不大于0.1时,2种方法均可满足施工精度要求;当高差系数绝对值大于0.1时,次档距线长积分法计算精度要优于次档距线长均分法。Based on skew parabola theory to solve sub-span line length through integration, a sub-span line length of a same example were calculated by sub-span line length integral and sharing method respectively. The results indicate when the height difference factor＇s absolute value is not bigger than 0.1. both ways can meet requirements of construction accuracy; when the factor＇s absolute value is bigger than 0.1. integral is better than the other one.
