摘要

Wushaoling railway tunnel, the longest single-track railway tunnel in China, is the key project ofrnLanzhou-xinjiang railway line. It goes through four regional faults (F4-F7). The geological andrngeostress conditions are quite complicated. According to the characteristics of soft rock tunnel withrnlarge deformation on complicated stress condition, comprehensive monitoring is executed inrnconstruction of Wushaoling tunnel. Based on the measured results of the crown settlement, thernhorizontal convergence, the axial force of rock bolt, the surrounding rock pressure, the stress in steelrnset, the stress in shotctete and the stress and pressure in the secondary lining, the relation betweenrnsurrounding rock pressure and displacement, the distribution rule of displacement, the coefficient ofrnlateral pressure, the shared ratio of secondary lining pressure, the construction time of secondary liningrnetc, are analysed in this paper. The above information is feedback to the construction in time. Thernstructure stability is analysed and the corresponding measures are adopted. It can also provide thernnumerical coefficients for data simulation and theoretical analysis. It is proved that the effect isrnreliable, the surrounding rock is stable and the structure is in good condition, providing a reliablerntechnical guarantee for the perforation of the section.
