| 摘 要： | 声发射作为一种地应力测试的方法,越来越引起人们的兴趣。应用岩石对经受应力历史具有“记忆”功能,作者利用声发射法对东营凹陷的岩样进行了测试,获得了该地区岩样的地应力记忆值和记忆出现率,从而来揭示本区所经历的构造期次和强度。测试结果证明,古应力记忆值与构造旋回中的应力历史是相吻合的。同时,在本文中简要介绍了声发射的基本原理。

| Abstract: | Acoustic emission as a method of measuring ground stresses has aroused increasing interset.Rock has the function of "memory" of its stress history.By using this function,the authors applied acoustic emission to the analysis of rock samples from the Dongying subbasin and obtained the ground stress memory values and memory occurrence rates and thus further revealed the phase number and intensity of tectonic activities that this area underwent.The results of the measurements demonstrate that the paleo-stress memory values coincide with the stress history in the tectonic cycles.Furthermore,the paper briefly introduces the basic principle of acoustic emission. |
