宁海白峤岭隧道设计

宁海白峤岭隧道是宁波市规划的高等级公路网中沿海南线公路的组成部分 ,为双向四车道 ,下行线隧道长 85 0m ,目前已建成通车。隧道地质条件较差 ,因而对隧道的施工、防排水要求较高。另外该隧道位于城区 ,要求隧道建成后两侧洞门与自然景观协调、富有特色 ,从而增加了设计的难度和复杂性。本文对该隧道的设计概况作一介绍

Design of Baiqiaoling Tunnel in Ninghai

Baiqiaoling Tunnel in Ninghai is the composition of the highway along the Hainan Line in high class highway network to be planned in Ningbo City. It is the two way four lanes and the length of the tunnel of turn down line is 850m which is built to traffic now. The tunnel has poorer geological condition, so the requirements in the aspects such as construction, waterproofing and drainage is higher. At the same time, the tunnel is located in the urban district, the tunnel door on two sides after completion of the tunnel shall be coordinated with the natural landscape with feature, therefore the difficulty and complexity of the design are added. The paper introduces the general of the tunnel design.
