| 摘 要： | 本文通过试验，证明了混凝土材料在往得加载过程中声发射过程凯塞效应和弗勒斯特效应的存在性。并对凯塞效应同弗勒斯特比的关系进行了详细研究。结果发现，混凝土材料在往复加载过程中其凯塞效应不仅具有应力上限，而且具有应力下降。

| Abstract: | In this paper the exsistence of Kaiser- and Felicity-effects and their relation-ship are studied by experiments on concrete specimens under cycle loading condition.Not only the exsistence of the upper stress limit of Kaiser effect is proved , but also that of the lower stress limit is detected .The upper stress limit is determined by the failure process and the lower limit is determined by internal structure of concrete material. |

| Keywords: | Concrete material Kaiser effect Felicity effect Stress limit |
