---According to the basic classification system of the bridge • Beam bridge, arch bridge, steel bridge, suspension bridge, slab bridge
Tห้องสมุดไป่ตู้e other classification of the bridge
The trend of the development of the bridge
• Bridge Span increasing • More and more kinds of Bridge • Structure light-duty
What is tunnel?
• A engineering structures which build in the formation of underground. It is widely used in highway, railway, mining, hydropower, municipal engineering and national defense, etc
The composition of the bridge
• Bridge span structure (Superstructure) • Bridge pier and abutment (infrastructure) • Pier foundation
The classification of the bridge

Bridge and tunnel engineering
What is bridge?
• Bridges is a kind of architectural structures for railways, roads, channels, pipeline, vehicles, pedestrians to cross rivers, valleys, lakes or other obstacles
The tunnel structure
• The main body structure: In order to maintain the stability of rock mass and driving safety and built artificial permanent structure, usually refers to the hole body lining and tunnel portal structure • Affiliated construction: Build for power generation, storage, maintenance, ventilation, lighting and other building construction
In 1969,China has attracted worldwide attention of Nanjing Yangtze river bridge which designed, constructed by oursleves. Railway bridge part is 6772 m and Highway bridge section is 4589 m. Nanjing Yangtze river bridge shows the Bridges in China has reached the advanced world level, also is another important symbol on our bridge history.
The main types of tunnel construction method
• Generally,tunnel construction can be divided into the open cut method and undercutting method
Open cut method
• Characteristic:first,dig all soil which in above of tunnel, and then build a tunnel lining, when necessary, laying type waterproof layer is stuck outside, and backfill it. Such as open hole and the method used in shallow buried tunnel or underground railway
The classification and function of the tunnel
• According to the stratigraphic points: rock tunnel, soil tunnel • According to the position: mountain tunnel, the urban tunnel, underwater tunnel • According to the purpose: traffic tunnel, the hydraulic tunnel, municipal tunnel, the mine tunnel
The basic purpose of bridge construction
Generally speaking, the bridge construction is the basic goal of safe, applicable, economic, beautiful. On the basic goals, it should be reflected in the development of bridge technology: Bridges with large span capacity and carrying capacity; Vehicle safety and passenger comfort.
· Materials used in the bridge:,masonry bridge,
reinforced concrete bridge, prestressed concrete bridge and steel bridge • Bridge application: highway bridge, railway bridge, iron bridge, pedestrian bridge, and pipeline bridge, etc
