- 摘要:
- 安宁河地区是我国地震活动的多发地带。通过对安宁河断裂带构造格架的研究，对发震机制进行了分析，在分析概念地质模型的基础上，进行三维数值模拟，证实了在现今区域应力场作用下，在5～10km深度范围内于断层交汇部位应力高度集中，因此，安宁河断裂带强震主要局限在于其它方向断层的交汇部位。
- Abstract:
- The Anning River region is an area where seismic activities occur frequently in our country.By studying the structure and the framework of the Anning River fault zone,the cause of the earthquakes in this area was analyzed,and the three-dimensional geological numerical simulation was used to prove that under the present regional stress there are concentrations of stress in the crossing of faults below the earth’s surface about 5~10 km,based on the studying of the notional geologic model.Hence the strong-motion earthquakes of the Anning River fault zone distribute the area where other faults with different direction joined in.
