摘　　要：建设中的龙潭特长公路隧道位于沪蓉国道主干线宜昌至恩施公路上,长约2×8.7km,为我国目前最长的双洞四车道隧道之一。在勘查设计过程中,充分借鉴了国内外长大公路隧道建设的成功经验,认真研究、精心设计,达到了技术上先进、质量上优良。文章简要介绍了龙潭特长公路隧道的工程概况、工程地质条件、隧道结构形式设计、衬砌及防排水设计、辅助结构设计、运营通风设计、监控和防灾方案以及关键技术研究等。Longtan tunnel under construction is a super long tunnel of about 8.7 km in length, located on Sharlghai-Sichuan national highway from Yichang to Enshi. It is at present one of the longest twin bore four-lane highway tunnels in China. In the reconnaissance and design phases, the authors fully adopted the successful experience in highway tunnel construction both in China and abroad, carried out extensive studies and a careful design. This paper briefly introduces the project, the geological conditions, the design of tunnel structure and lining, the design of waterproofing and drainage system, the design of auxiliary installations, the design of operation ventilation, the monitoring and fire protecting system of the project and the research activities on some key techniques.
