| 摘 要： | 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。

| Abstract: | Based on the comprehensive analysis on geological environment and fault zone distribution in the Bohai sea meizoseismal area, we made the geological model by using polycarbonate material to simulate the specific structural framework of stress and strain fields. In the simulation, uniform, concentrated and two-point loading are applied in photoelastic experiments. The seismic risk area in the Bohai sea meizoseismal area is determinated through photoelastic experimental data analysis and processing, which is based on the comparison of stress accumulation area and seismic hazard points in different loading ways. |
