摘　　要：随着隧道施工机械化程度的提高,在特长小断面隧道工程中采用钻爆法掘进施工时,机械配套是制约掘进速度的重要条件。文章介绍了西康线秦岭隧道Ⅱ线平导进口工区,在分阶段采用不同的机械配套的条件下,发挥了配套机械的整体工作效能,给类似工程提供了一个典型实例。With the increase of mechanization level in tunnel construction, matching of machine becomes an important condition that determines tunneling speed in the construction of extra-long and small cross section tunnel. In guiding entrance area construction of Qinling tunnel No.2 line of Xikang line, different philosophy and mode of machine matching are adopted at different stages, so that overall operating efficiency of matched equipment is explored, which provides a typical example for similar projects.
