【摘要】：总结我国隧道及地下工程近两年的发展情况。1)铁路、公路、地铁、水工等主要领域的隧道总数和总长度快速增长。2)重难点隧道及地下工程建设进展顺利:青藏铁路关角隧道、兰新高铁祁连山隧道、兰渝铁路木寨岭隧道、烟台地下水封LPG洞库、渝黔高铁天坪隧道等相继完工;港珠澳大桥沉管隧道、引松供水隧洞、引汉济渭输水隧洞、武汉三阳路长江隧道、大瑞铁路高黎贡山隧道、京张高铁八达岭地下车站、惠州地下水封油库、湛江地下水封油库、珠海横琴地下综合管廊等在如期建设中。3)特长山岭隧道建设技术、软岩隧道大变形控制技术、高瓦斯隧道建设技术、岩爆隧道建设技术、大断面矩形顶管及矩形盾构设计与应用技术、隧道机械化施工水平等方面取得了进一步的突破。我国隧道及地下工程修建技术整体处于国际先进水平。国家新型城镇化建设、新一轮西部大开发、"一带一路"、海绵城市、城市地下综合管廊、城市轨道交通、京津冀协同发展、长江经济带、珠三角经济区等战略规划,为我国隧道及地下工程领域技术发展带来了前所未有的契机。最后,基于隧道及地下工程发展方向,指出超长隧道技术,高地应力软岩大变形控制技术,高水压、大断面水下隧道建设技术,高地温、高地热隧道建设技术,高地震烈度与构造活跃带的隧道建设技术,隧道运营维护管理技术,新材料研发与应用的开发等是今后需要深入研究的关键课题。
[Abstract]:This paper summarizes the development of tunnels and underground projects in China in the past two years. 1) the total number and total length of tunnels in the major fields of railway, highway, subway, hydraulic engineering, etc., are growing rapidly. 2) the construction of heavy and difficult tunnels and underground projects is progressing smoothly: the Guanjiao Tunnel of the Qinghai-Tibet Railway, The Qilian Mountain Tunnel of Lanxin High-speed Railway, the Muzhai Ridge Tunnel of Lanzhou-Chongqing Railway, the LPG tunnel of Yantai underground water seal, the Tianping Tunnel of high-speed railway between Chongqing and Guizhou, the sinking pipe tunnel of HongKong-Zhuhai-Macao Bridge, the diversion of water supply tunnel, the diversion of Han Ji-Wei water conveyance tunnel, Wuhan Sanyang Road Yangtze River Tunnel, Da-Rui Railway Gaoligongshan Tunnel, Beijing-Zhang High Speed Rail Badaling Underground Station, Huizhou groundwater Oil Seal Depot, Zhanjiang groundwater Oil Seal Depot, Zhuhai Hengqin Underground Comprehensive Pipe Corridor is under construction on schedule. 3) the construction technology of mountain tunnel, the control technology of large deformation of soft rock tunnel, the construction technology of high gas tunnel, the construction technology of rock burst tunnel, Further breakthroughs have been made in the design and application technology of large section rectangular pipe jacking and rectangular shield tunneling, the level of tunnel mechanization construction, etc. The construction technology of tunnels and underground works in China is at the international advanced level. A new round of western development, "Belt and Road", "sponge city", urban underground integrated management corridor, urban rail transit, coordinated development of Beijing-Tianjin-Hebei, Yangtze River economic belt, Pearl River Delta economic zone, etc. It has brought an unprecedented opportunity for the development of tunnel and underground engineering technology in China. Finally, based on the development direction of tunnel and underground engineering, it is pointed out that the technology of super long tunnel, the control technology of large deformation of soft rock with high ground stress, and the high water pressure, Large section underwater tunnel construction technology, high ground temperature, high geothermal tunnel construction technology, tunnel construction technology with high seismic intensity and active structural zone, tunnel operation maintenance and management technology, The research and development of new materials and applications are the key topics to be studied in the future.
