预应力锚索设计与施工中几个问题的探讨

On prestressed anchor cable design and some problems in construction

针对预应力锚索的设计施工是受多方面因素制约的,结合工程实际,对预应力锚索锚固段长度确定、锚索设置、二次注浆、锚索张拉等几个要点从多方面进行了探讨,并提出了相应的方法措施,从而推广预应力锚索加固技术的应用。

Aiming at that the design and construction of the prestressed anchor cable is restricted by multiple factors, and combining with projeer practice, the author discusses the length determination of the prestressed anchor cable section, anchor setting, secondary grouting, anchor cable extension from many aspects, and provides corresponding methods and measures, so as to promote the application of the prestressed anchor cable reinforcement technology.
