摘要
在简要地介绍了数字云纹法应变测量的基本原理以及实施方法的基础上,对这一方法在岩石材料上应用的可行性进行了验证,通过对粉砂岩、泥贞岩、片麻岩及大理岩四种岩石弹性模量的测定,说明运用数字云纹法可对不同特性岩石材料进行测试,其精度能满足丁程要求。是电阻应变片测试方法的有益补充。
On the basis of introduction of the baic principle and application of the digital moire method, the possibility of application of this method to the rock materials is studied. In the mean time, the Young's moduli of several kinds of rocks such as mud-shale, gneiss, siltstone and marble are surveyed using this method and strain gauge method. The results show that digital moire method fulfils the accuracy requirement and it could remedy the defects of strain gauge.
