核电厂安全壳预应力锚具静载试验

核电厂安全壳大吨位预应力锚固系统是核电站安全壳施工中重要的、复杂的部分，锚具的静载锚固性能通过钢绞线—锚具组装件的静载试验来衡量。根据核电设计单位要求，核安全壳预应力锚具静载试验时应模拟实际工况，在端部增加砼锚固块，这与常规锚具静载试验相比，纲绞线在砼锚固块处产生弯折，这大大增加了试验的难度。本文介绍模拟实际工况下核安全壳预应力锚具的静载试验，试验的成功促使了国产核电预应力锚具的应用。

Static load test of prestressed anchorage for nuclear power plant containment

The large-tonnage prestressed anchorage system for the safety shell of nuclear power plants is an important and complex part of the construction of the safety shell. The static anchoring performance of the anchorage is measured through static load tests of the steel strand anchorage assembly. According to the requirements of the nuclear power design unit, the actual working conditions should be simulated during the static load test of the prestressed anchor of the nuclear safety shell, and concrete anchor blocks should be added at the ends. Compared with the conventional anchor static load test, the steel wire strands bend at the concrete anchor blocks, which greatly increases the difficulty of the test. This article introduces the static load test of prestressed anchors for nuclear safety shells under simulated actual working conditions. The success of the test has led to the application of domestically produced prestressed anchors for nuclear power plants
