摘　　要：隧道钢拱架质量的好坏,主要决定因素是钢拱架的焊接质量。文章通过查阅关于硬钎焊的相关文献资料,对隧道钢拱架材质及焊接性进行了分析,并以工字钢钢拱架为例进行了硬钎焊工艺设计研究,以期为隧道支护安全设计提供参考依据。The quality of tunnel steel arches is mainly determined by the welding quality of steel arches.This article discussed the material and weldability of tunnel steel arches by referring to the relevant literature on brazing,and studied the brazing process design research with the I-beam steel arch as the example,hoping to provide the basis for the tunnel support safety design.

关 键 词：隧道钢拱架 硬钎焊 工艺设计
