施工难点r line is a step valley the especially big project of tune water bear to the water supply of the important cities such as Beijing and Tianjin and along the significant tasks such as the farmland irrigation of line. Design major is aim at the project of center line Wu village tunnel design as well as construction organization compile.
Design includes 3 parts totally: Tunnel construction organization and the design of introduction and tunnel compile. In which, it is the first to divide into introduction to include: Project total general situation, topography landforms, hydrology and the difficulty of geology and project and characteristic some parts of; The design of second partial tunnels includes: Design basis and scheme than choose, structural design (include tunnel lining build the design of design and hole door with Jian calculate ); The partially tunnel construction organization of 3th compile to include: Construction preparation and tunnel are under construction ( include project quantity and construction method ) , the defence of structure and the plane disposition of place drain , environmental protection, monitoring instrumentation as well as construction quality guarantee measure.
In appendix, have included the translation of professional English and some related blueprints of tunnel design.

1 绪论
我国是一个幅员辽阔的国家，南北跨越几千公里；但是我国的水资源分布极其不平衡：南方多雨且易形成洪涝灾害，而北方却非常干旱，经常出现旱灾。随着我国经济的不断发展，缺水已经成为制约我国经济发展的重要因素。为了解决这一难题，我国制定了南水北调的重大工程规划。
南水北调工程是我国西部大开发的标志性工程，其中中线工程是一项跨流域调水的特大工程担负着向北京。天津等重要城市的供水及沿线的农田灌溉等重大任务。
中线工程的吴庄隧洞长2475米，是整个中线工程中最长的一个隧洞，它的设计与施工直接制约着整个中线工程。同时吴庄隧洞无论从隧道的长度，还是从隧道施工的难易程度上来说，在我国类似的工程都还很少，可以借鉴的类似工程事例不多，这对隧洞的设计与施工带来了不少困难，我们选择这个课题是为了能够尽力用所学的知识来对南水北调工程的设计做出一点贡献。
在设计时，我们对隧道的形式提出了两种不同的设计方案：分离式双洞、双连拱隧
