| Abstract: | With the geological characteristics of the large-cross-section loess tunnel of the Tai-Zhong-Yin Railway taken into account,the-ring-shaped-pilot-hole-with-the-core-earth-pre-retained method and the three-bench method are adopted for the excavation operation of the tunnel,the main construction processes of which are dealt with in the paper,with stress placed on the introduction to the initial supporting and retaining for the tunnel,2nd lining,water prevention and draining during construction,and the control techniques for settlement-caused deformation.It may serve as a useful reference for the safe and high-speed construction of loess tunnels. |
