随着我国水电事业的迅速发展,一些大型水力枢纽工程的兴建,水工预锚技术的规模愈来愈大,特别是300～600吨大吨位级预应力锚索的实践,已开始显示出我国水利水电工程中应用预应力技术的新貌.为了促进水工预锚技术向更新更高水平发展,本文就水工大吨位预应力锚固技术应用实践、锚索体材料、预应力体系、预应力度选择、张拉控制应力取值、施工工艺等一些方面作一一浅述.最后,提出笔者从事预锚技术实践中所想到的几个问题.不当之处,恳请指正.

With the rapid development of hydropower in China, the construction of some large-scale hydraulic hub projects has made the scale of hydraulic pre-anchoring technology more and more large. In particular, the practice of 300-600 tonne large tonnage prestressed anchor cables has begun to show that our country In order to promote the development of hydraulic pre-anchor technology to newer and higher level, this paper discusses the application of large-tonnage prestressed anchor technology, anchorage cable material, prestressing system, prestressing force Selection, tension control stress value, construction technology and so on.Finally, I put forward several problems that I think of in the practice of pre-anchoring technology.Inappropriate, please correct me.
