“割线法”在曲线巷道的应用

Application of "Secant Method" in the Curve Roadway

文中详细介绍了"割线法"在曲线巷道中心线标定中的应用,并在阐明分段计算方法的基础上,编制了"割线法标定分段数据表",证明了"割线法"比"短弦支距法"精度高,且简便易行。

In the paper,the author introduces the application of 'secant method' in demarcating the central line of curve roadway in detail. The author develops ' demarcate Segmented data table by secant method' on the basis of expounding the piecewise calculation method, and proves that the secant method is higher precision and easily obtained than the short chord offset method.
