摘　　要：某中型水库枢纽工程,在导流洞出口边坡开挖过程中,由于导流洞出口边坡出现地质缺陷问题,项目部采取新增预应力锚索、锚筋束及进洞口管棚等方式进行支护。论文主要介绍了其中的预应力锚索施工工艺,包括技术参数、主要施工材料、施工流程、工艺方法等,并提出特殊情况下的处理措施。In the process of excavation of diversion tunnel exit slope of a medium-sized reservoir junction project, due to the geological defects of diversion tunnel exit slope, the project department adopts new prestressed anchor cable, anchor bar bundle and pipe shed for support. This paper mainly introduces the construction technology of prestressed anchor cable, including technical parameters, main construction materials, construction flow, technology methods, etc., and puts forward the treatment measures under special circumstances.
