桥梁改建施工关键技术探讨

Key Technique of Bridge Reconstrucion

随着我国经济的日益发展,现有桥梁的交通量随之增长,很多早期修建的桥梁明显满足不了交通需求,桥梁改建将成为重点工程项目。通过介绍桥梁改建施工的一些关键技术问题,提出桥梁改建应结合不同桥梁的地理特点和原有设计特点,制定出合适的改建方案,同时列出施工实施注意事项,保障桥梁的质量和延长桥梁的使用寿命。

With the increasing development of China^s economy, the existing bridge traffic grows, and a lot of early-constructed bridge obviously can not meet the traffic demand, so bridge reconstruction becomes the focus of the project. By introducing some key techniques of bridge reconstruction, this paper puts forward that a right recontruction plan should be developed according to the geographical features and original design of different bridges, with listing items need attention, so as to guarantee the quality of the bridge and extend the life of it.
