摘　　要：以东海煤矿32#下延巷断面设计为例,提出了底板任意三心拱拱高确定和图形绘制方法。利用ANSYS分析软件,确定巷道底板三心拱的合理拱高;利用AutoCAD绘图工具,借助于内切圆确定三角形内角平分线交点,通过圆弧和镜像命令完成三心拱的绘制。By taking 32# decurrent roadway section of Donghai coal mine as an example, methods of determining arch height and graph rendering are put forward. The appropriate arch height is determined with ANSYS analysis software. Internal angle bisector intersection of triangle is determined by inscribed circle position with AutoCAD drawing tools and drawing of basket-handle arch is completed by using arc and mirror command.

关 键 词：底板三心拱 拱高确定 三心拱绘制
