摘　　要：泥质白云岩作为一种软岩广泛分布于贵州各地,近年来随着贵州建设的大力推进,其力学性质越来越受到学者们的关注。本文采用一种新的光学技术—数字散斑相关技术来观测泥质白云岩的单轴压缩过程,首先对数字散斑相关技术中的散斑制备和相机架设进行了阐述,其次对试验结果中的应变云图进行了解释。As a kind of soft rock,muddy dolomite is widely distributed throughout Guizhou Province. In recent years,with the vigorous promotion of Guizhou construction,its mechanical properties have attracted more and more scholars＇ attention. A new optical technique,digital speckle correlation technique,was used to observe the uniaxial compression process of muddy dolomite. The speckle preparation and camera setup in digital speckle correlation technique were described. Then the strain cloud was explained.
