摘　　要：指导曲线巷道掘进通常用弦线代替中线,弦线距两帮的距离即边距是指导施工的关键参数,针对常用的图解法量算边距工作量大精度不高的缺点,利用等分圆心角法将曲线最优化分为几个相同子曲线,提出解析法计算边距并用软件实现,提高了运算速度和施工质量。Analytical Calculation and Software Realization of Curve Tunnel Margins- Guiding curve Tunneling usually used strings instead of the center line,and the margin that the strings were distance from the two strings was the key parameters guiding the construction. The author proposed analytical method to calculate margins and used software to implement for the shortcomings of workload and low accuracy by the commonly graphic method,divided curve into several identical sub- curve using the aliquot of central angle method. Computing speed and construction quality were improved.
