预应力筋──锚具组装件锚固性能的静载试验方法

THE STQTIC TEST METHOD FOR ANCHOR BEHAVIOR OF AN ASSEMBLED TENDON

近几年来，笔者结合科研和生产需要，通过对钢丝、钢铰线及其镦头锚具、ＪＭＦ锚具和钢质锥形锚具等不同预应力筋张拉锚固体系进行了大量预应力筋－锚具组装件的静载锚固性能试验，在量测仪器和试验方法上进行了专门研究和改进，对影响锚具锚固性能的各有关参数全部采用自动量测系统进行实测，获得了较好的实验结果，为制定国家标准和实际生产应用提供了大量可靠数据。

For the various available anchorage system(button head anchorage and wires,JMF anchorage and strands,Freyssinet anchorage and wires) the static test of an assembled tendon must be carried out to meet with the needs for production and researching.The static test method has been studied, and the measuring instruments has for improved specially by author in recent years.The related data which affects the anchor behavior of anchorage is measured automatically.The test atesults and data got in testing can be used as reference to national code and production.
