| Abstract: | The article introduces the application of the multi-arch tunnel construction technology by central drift method in the construction of Longzikang Multi-arch Tunnel of Jishou~Huaihua Expressway Contract Section 4.Based on the past three-pilot drift method,the side pilots at two sides are canceled in the surrounding rock section above Class IV and the central drift method is directly used in the construction,which simplifies the construction procedure,decreases the investment and seeps up the construction schedule. |
