应用激光散斑摄影术形成多张二次曝光散斑图系统,测定了四川九龙山地质构造相似模型的三维位移场,并据此分析了该构造可能存在裂缝的位置分布,为油气勘探提供了一定的实验依据。实践表明,这种方法在研究地质结构方面具有广阔的应用前景。
A laser speckle photography technique was used to form multiple secondary exposure speckle patterns. The 3D displacement field of the similar model of Jiulongshan geological structure in Sichuan Province was measured. Based on this, the location of possible fractures in the structure was analyzed, A certain experimental basis. Practice shows that this method has broad application prospects in the study of geological structure.
