全息干涉法研究岩石裂隙扩展破坏规律

Study on the laws of rock crack expansion and destroyed by holographic interferometry

将全息干涉计量术应用到岩石裂隙实验测量方面，获得了岩石试样微裂隙起始开裂、扩展变化及破坏全过程的特征干涉条纹图谱。直观、形象地表示出微裂隙的变化。这是常规实验方法难以实现的。

In this paper,the method of holographic interferometry is used to analyze qualitatively the deformation laws of the rock crack.The characteristic interference fringes of all processes of the rock crack expansion and destroyed have been record.It can directly and viridly depict the deformation laws of rock crack under the action of outside force.
