On the Portal Construction Technology of Spiral Tunnel in Special Stratum

Abstract:

Abstract: Xigeda stratum is a kind of extremely soft rock with bad engineering property and its rock easily gets soft when wet which gives rise to geologic hazard, thus side and heading slope excavation at tunnel opening often causes collapses. Based on the construction technology of Gan Haizi tunnel in Yaxi express way, this thesis will first analyze its strata characteristics, and then focus on the methods of stabilizing side and heading slope, as well as the effective means to avoid opening deformation, so that the construction and operation can be carried out safely.
