摘　　要：在矿山井巷工程设计与施工过程中,平巷与斜巷的交接部位一般采用竖曲线进行连接和过渡。竖曲线部位的施工,相对于平巷、斜井而言,施工质量难控制。为此,采用"距离-倾角法",直接标定竖曲线腰线,指导工程施工。实践证明,该方法计算简单,操作方便,较为实用。In the process of design and construction of mine shaft engineering, we generally use vertical curve to connect and transform for the crossing points of drift and inclined shaft. The construction quality of vertical curve is difficult to control in terms of the drift and inclined shaft. For this reason, the paper uses＂ distance-angle method＂ to calibrate the waistline of vertical curve directly, and guides the engineering construction. The facts have showed that the method is simple and effective, and easy operation.
