浅谈桥梁施工中预应力技术的应用

Elementary Discussion on Application of Pre-stressing Technology in Bridge Construction

在我国的道路桥梁建设中预应力技术作为一种施工技术有着较为广泛的应用。其主要原因是预应力技术具有其他施工技术难以比拟的优点。它可以在减少自身结构的重量的同时,使得建材的最大强度得到了有效利用,同时使桥梁跨度得到增加。但是为了确保预应力技术可以在桥梁得到很好的应用,仍需要施工人员在进行施工和方案设计方面精益求精,对施工人员的技术及质量控制也要求较高,其工艺复杂是预应力技术施工的一大特点。该文结合实际工程,分析了预应力技术在桥梁施工中的要点,其目的是为了可以在一定程度上改善桥梁的施工质量。

The pre-stressing technology,as a construction technology,is more widely used in the road and bridge construction in China.The main reason is that the pre-stressing technology has the advantages the other construction technologies are hard to compare.The technology can make the maximum strength of the building materials effectively utilized and also make the bridge span increased while its structure weight is decreased.But in order to ensure the pre-stressing technology able to be better applied in the construction of bridges,the construction members are still required to perfect the construction and scheme designs,and the technology of the construction members and the quality control are also highly required.The complexity of the technology is a great characteristic of pre-stressing technological construction.Combined with the practical cases,the article analyzes the gist of the pre-stressing technology in the bridge construction.Its aim is to improve the bridge construction quality to some extent.
