| Abstract: | In Guan Yin Shan tunnel construction of Dongjiang Shenzhen water supply modification works, based on the theory of NATM, by employing the techniques such as joint supports and wall rock measurement, the bad geologic sections within the tunnel portals have been successfully cut through. In the construction of types Ⅱ and Ⅲ wall rocks, good explosive results have been achieved. This paper discusses the definition of joint support and smooth blasting parameters and the management of wall rock and support structure deformations. |
| Keywords: | tunnel construction NATM joint support smooth blasting |
