摘要: 针对巷道交岔点建模的难点问题,采用基于巷道底板中线加载巷道断面的方式绘制单一巷道体,提出了根据巷道设计参数的方式对柱墙式交岔点进行建模。并依据穿尖式交岔点和马门头中两条巷道自然相交的特征,对二者进行建模。最后通过C#结合DirectX的编程方式进行验证,结果表明所绘制的巷道交岔点外观规整并形成连通。

Abstract: Regarding to the difficulties on modeling roadway junction, the single tunnel is modeled by loading section with the centerline of roadway. Besides, a way based on the design parameters to model roadway junction is proposed. On the basis of directly intersecting feature of both roadway junction and horsehead, they are modeled respectively. Finally, the feasibility of the algorithms is verified by C# and DirectX programming practice, and the experiment results are presented in the paper.
