Application of the CRD Method in Construction of an Ultra-Shallow, Ultra-High Section and Large-Span Mined Tunnel

Abstract:

This paper explain the controllable factors of the application of the CRD method in the construction of an ultra-shallow, ultra-high section and large-span mined tunnel. And it also introduce the construction scheme of the application on the background of the Ou-Zhuang station air duct C of Guangzhou Metro line No.5. The practical application shows that the CRD method is not only an applicable method but also a necessary means for this kind of tunnel.
