| Abstract: | Wansongling tunnel, located in Hangzhou, China, is a large spanned highway tunnel containing 4 lanes in both directions. Due to the large cross section, large span, shallow cover, complex engineering geological conditions and complex surrounding environment of the tunnel, there exist great difficulties in the construction of the tunnel. By means of such key construction technologies as ground pre consolidation performed from inside tunnel, double side drift construction method and micro vibration blasting, the tunnel has been completed safely and successfully and good economic and social efficiency has been achieved. |
