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.

Tunnel development technology
• The fourteenth century --The invention of gunpowder used in tunnel excavation
• In 1818, Tunnel Boring Machine(TBM) was invented in Brussels
2
The composition of the bridge
• Bridge span structure (Superstructure) • Bridge pier and abutment (infrastructure) • Pier foundation
3
The classification of the bridge
7
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
· 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
---According to the basic classification system of the bridge
• Beam bridge, arch bridge, steel bridge, suspension bridge, slab bridge
4
The other classification of the bridge
