采场围岩移动规律的激光全息云纹干涉实验方法

ON STUDY DIGGED FIELD MOVEMENT'S LAW BY EXPERIMENTAL METHOD OF LASER HOLOGRAPHIC MOIRE INTERFERMETRY

本文首次成功地将高精度的光测力学位移测试技术应用到模拟地层的新型变弹模的相似模型上,并测定了上下岩层的移动角及上下岩层的位移分布情况。这测技术是激光技术和现代化学粘结剂的成就结合——贴片云纹干涉法。它与实测相比,结果是令人满意的。

The high-precision displacement measuring technology of optic-measuring mechanics is, for the first time,successfully applied on the similar model of the model land-layer with a new-type variable modulus of elasticity. The angle of movement and the distributed displacement of upper and lower rock-layers are measured. The technology is a combination of laser's technology and the modern chemical sticker-it is called the sticking moire interferometry. Compared with the measured values, the result is very satisfactory.
