影像云纹法的原理及其在工程地质中的应用

本文扼要阐述了影像云纹法的光学原理和离面位移的计算方法。在大量试验的基础上设计了影像云纹仪。该仪器可用于三维外形和离面位移场的测量,为岩体结构面的起伏测量、地质力学模型试验、试样制备检验等方面提供一种有效途径。此外,还结合实例介绍了测量方法和仪器性能。

THE PRINCIPLE OF SHADOW MOIRE METHOD AND ITS APPLICATION TO ENGINEERING GEOLOGY

This paper expouds the optical principle and the calculating method of the off-plane displacement of shadow moire method. On thebasis of many of experiments a shadow moire instrument is invented. It can be used for measurement of three dimensional forms and off-plane displacement and provides an efficient way in the profile measurement of discontinuity, the model tests of geomechanics and theexamination of samples. Lastly, the measurement way and instrument behaviors are introduced by an example.
