摘　　要：介绍无粘结筋———锚具组装件在低温下疲劳锚固性能试验的有关情况。试验结论可以消除人们对于在寒冷环境修建无粘结预应力混凝土结构所存的疑虑 。The result of the fatigus anchorage property test of compound body of unbounded prestressed bars and anchorage devices in low temperature was introduced in this paper. The conclusions of the test can dispel misgivings to unbounded prestressed concrete structures built in cold environment test, and pave the way for spreading this technique.
