The article expounds how the soft country rock in the construction of the Feiluanling Tunnel is dealt with according to the construction principles of the New Austrian Method by using construction ways of digging piece by piece on the upper half section, in-advance filling the concrete, propping up with pipe canopy and dealing with collapsing.
