| 摘 要： | 断裂构造的活动是地震的成因之一。断裂构造上的小震速度结构分布为人们准确提供了地下壳质结构模型,为断裂的活动性分析提供了依据。文中结合太行山南端的地震台网监测资料,利用小震P波走时数据,通过震源和速度结构的联合反演,确定了太行山断裂构造南端的三维速度结构模型。结果表明: 太行山山前断裂带的西侧存在NNE向断层,速度结构平面分布显示低速区沿断裂带呈条带状分布,太行山隆起区沉积层厚度由8km左右逐渐减薄为2km左右,同时受西侧作用力的影响地壳厚度逐渐增厚。

| Abstract: | The activity of fault is one of the causes of earthquakes.The distribution of the velocity structure of small earthquakes on the fault structure can offer an accurate underground crust structure model for us to analyze the activity of fault.Using the seismic network monitoring data at the southern end of the Taihang Mountains and the small earthquake P wave travel time data,the paper reconstructs the three-dimensional velocity structure model for the southern end of the Taihang Mountains Fault zone by joint... |
