摘要: 激光全息光弹法引入地质断裂模拟实验,可简化平面构造应力场的分析.实验初步结果表明,在等和线密集处,与历史地震分布有较好的对应.新技术为地震危险区的圈定提供了新途径.Abstract: To simplify the analysis of the tectonic stress field in plane, holographic inter-ferometry has been applied to model experiments. Preliminary results from these experiments show that clustering of lines of equal sum of stress corresponds approximately with the distribution of historical earthquakes. This new technique has obviously through light upon better regionalization of earthquake risk areas.
