| 摘 要： | 采用浅层地震反射勘探方法对南秦岭构造带内丹江断裂进行地球物理勘探，通过数据处理与分析，获取包括断裂在隐伏区的几何展布形态、上断点埋深及断层性质在内的高分辨率浅地震剖面；对部分测线的地震剖面成果与钻孔资料进行对比验证解译。研究表明，浅地震反射对该区域隐伏探测行之有效，该方法可为隐伏活动断层探测提供参考。

| Abstract: | The shallow seismic reflection method is used in the geophysical exploration of the Danjiang fault in the southern Qinling mountains tectonic belt. Through data processing and analysis, high resolution shallow seismic profiles with characteristics of geometric distribution, breakpoint burying depth and fault properties are obtained. In this paper, the results of seismic profiles and drilling data of part lines are verified by comparison. The results show that the shallow seismic reflection is effective for the hidden detection in this area, and this method can provide reference for the detection of buried active faults. |
