A summary of the development of travelling trestle bridge fabrication machine in China |
| |
| Abstract: | The development of travelling trestle bridge fabrication machine in China was reviewed. Bridge fabrication machines were classified according to PC box girder's position in travelling trestle. A comparison was made between two construction methods: precast girder assembly method and cast|in|situ method. Explorations and analysis were also made of travelling mode of bridge fabrication machine, adaptability of the machine to curved PC bridges, and bracket around pier. |
