我国长大隧道施工发展趋势探讨

随着我国铁路、公路、水利等基础设施建设的加快，长大隧道（洞）的数量越来越多。对长大隧道施工的发展趋势进行了展望，提出需从八个方面予以重视和研究，包括提高机械化水平、减少辅助坑道改变长隧短打、推广TBM法、二次衬砌跟进及TBM掘进与二衬同步施工技术研究、恶劣地质条件下安全快速施工技术、超前地质预报及围岩监测、重视环境保护与水土保持、重视信息化管理的应用，以此来推动我国长大隧道施工技术的更大进步。

Discussion of Development Trend of Long Tunnel Construction in China

With the development of China＇ s railway, highway, water conservancy and other infrastructure construction ac- celerated, grew up in the tunnel （hole） in the growing number of tunnel construction on the development trend of growing up were prospects fi＇om the eight areas that require attention and studies, including raising the level of mechanization, to reduce the auxiliary tunitel to change the long tunnel bunt to promote the TBM method, secondary lining to follow up and TBM boring lining with two simii｜taneous construction technology, in poor geological conditions, safe and fast construction technologies, geological prediction and its surrounding rock monitoring, attach importance to environmental protection and soil conservation, emphasis on information management applications, in order to promote the tunnel construction technology greater progress in our country.
