摘要
杭州万松岭隧道为双向四车道大跨公路隧道,断面大、结构扁平、埋深浅且工程地质和周边环境条件复杂,施工难度大。通过采取洞内地层预加固、双侧壁导坑法施工和微振爆破等关键技术,保证了工程安全顺利建成,并取得了较好的经济效益和社会效益。
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-eonsolidation 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.
