                华东地区最长公路隧道——杭绍台高速公路大盘山隧道打通,尊龙官网台州两地建设者胜利会师

                       7月1日,华东地区最长公路隧道——杭绍台高速公路大盘山隧道打通,尊龙官网台州顺利会师,标志着杭绍台高速建设取得了突破性进展。大盘山特长隧道全长8650米,其中尊龙官网方负责施工1759米,台州方负责施工6891米,此隧道的贯通为整个杭绍台高速公路的顺利完工奠定了坚实基础。 

                    大盘山隧道是杭绍台高速全线的重难点工程和控制性工程,隧道进口位于尊龙官网市新昌县回山镇,出口位于台州市天台县街头村。隧道地质构造及水文条件复杂,穿越多条断层,进口段场地狭小,开挖方向为反纵坡,施工中弃渣和排水困难,施工难度极大。
