摘要:

台9线苏花公路沿线地质条件复杂,加上濒临太平洋及受东北季风、雨水冲刷影响,经常发生落石崩坍,导致道路中断。为提升公路行车安全,给东部民众提供一条安全回家的路,为此特推出台9线苏花公路改善计划。苏花改计划全长388 km,其中有8座隧道(约243 km)均是变质岩。由于隧道沿线地质条件不易掌握,且隧道开挖后出现地下涌水,施工中遭遇灾害的频率与风险相对增加,而长隧道(大于3 km)施工又较一般隧道工程艰难。因此,针对苏花改工程观音及谷风隧道施工管理做以介绍,并对台铁旧北回隧道进出采用的RFID、号志人车管制、施工作业方式、高风险管控、开挖面地质预判、地下水处理及计测结果加以探讨,希望本工程的施工经验使工程界对台湾东部变质岩长隧道施工有进一步的了解。

Abstract:

Due to limitations in difficult geography and geological conditions, existent main channel toward north in eastern Taiwan, Highway No. 9, in general has many steep slopes and sharp curve. Road serviceability and capability are both low herein and the traffic is often interrupted by largescale landslides once the typhoon or heavy rain comes. In order to further improve conditions stated above and then provide a safe way to residence in eastern Taiwan home, Directorate General of Highways started the Suhua Highway improvement project. The whole route length is 38.8 km and among them, eight tunnels in total with 24.3 km in length will be constructed in metamorphic rock. Special attentions have been paid for the decision of details of the tunnel design and construction and potential risks caused by tunnel construction have been significantly minimized. This article will focus on construction processes and management in Guanin and Gufong tunnels, continuing 12.6 km in length, such as RFID (Radio Frequency Identification), tunnel portal traffic sign, tunnel high risk administration, geological exploring, underground water treatment and related monitoring.

Key words: Suhua highway improvement project, metamorphic rocks, long tunnels
