本文在对渤海强震区地质构造环境、断裂带分布特征进行详细分析的基础上,采用机械加工聚碳酸酯材料制成渤海强震区域的地质模型,分别运用集中、二点和均布加载方式,用光弹实验方法模拟特定构造框架下应力、应变场的变化特征。通过对光弹实验数据的分析与处理,在对比不同加载方式下应力积累区域和地震危险点的基础上,判定渤海强震构造区中的地震危险区域。
Based on the detailed analysis of the geological tectonic setting and the distribution characteristics of the fault zone in the strong earthquake area in Bohai Sea, the geological model of the strong seismic area in the Bohai Sea is made by machining polycarbonate materials. By using the centralized, two-point and uniform loading methods , The photoelastic experiment method is used to simulate the changing characteristics of stress and strain field under a specific structural framework. Based on the analysis and processing of the photoelastic experiment data, the seismic hazard areas in the strong seismic tectonic area of Bohai Sea are judged on the basis of comparing the stress accumulation areas under different loading methods and the seismic hazard points.
