| 摘 要： | ＡＥ检测是对混凝土的疲劳破坏进行监测与预报的有效方法，它作为一种动态无损检测方法几乎不受材料的限制，本研究对水泥砂浆试作（φ１０ｃｍ×２０ｃｍ）进行等幅低频部分片振压缩疲劳实验，结合应变进行ＡＥ测试，从而阐明混凝土在疲劳损伤中的ＡＥ特性，为在实践中应用推广ＡＥ技术奠定试验基础。

| Abstract: | Being a kind of dynamic un-damaging detecting method, AcousticEmission is almost applicable of all materials. Based on the const-amplitude partly low-frequency compress fatigue test carried out on cement mortar samples (φ10cm×20cm), some analysis and inspections on its strain and AE test results have been performed to explain the basic fatigue characteristics of concrete and the AE characteristics of concrete during the fatigue damaging process. Thus, a test foundation has been laid for the application of AE un-damaging test technique. |
