宁波市机场路大型隧道设计与施工关键技术

Key Technologies of Design and Construction of Large Tunnel in Ningbo Airport Road

宁波夏禹路隧道工程位于浙江省宁波市海曙区,为机场快速路与铁路南站连接线的一部分。隧道主线为双向4车道城市快速路,并设双向4车道地面辅道。本重点工程连通铁路南站枢纽与城市快速路网系统,为铁路南站提供一条进入城市快速路系统的客运专用通道,满足枢纽交通集散需求。结合该隧道实际情况,就该隧道设计施工中的重难点进行了分析并提出了应对措施。

The Xiayu Road tunnel project in Ningbo is located in Haishu district.The tunnel is a part of the connecting line between the airport expressway and the south railway station.The main line of the tunnel is a two-way 4-lane urban expressway,with two-way 4-lane ground auxiliary road.This key project connects the south railway station hub with the urban expressway network system,which provides a dedicated passenger passageway for the south railway station to enter the urban expressway system for meeting the demand of hub traffic distribution.Combining with the actual situation of the tunnel,this paper analyses the important and difficult points in the design and construction of the tunnel and puts forward the corresponding measures.
