| 摘 要： | 高分辨率浅层地震勘探技术能够较准确地探测活动断层的位置、性质,并初步研究断裂的活动性。作者在夏垫断裂上采用不同激发震源、不同道间距、不同观测系统参数的探测方法,获得了多条高质量叠加时间剖面图,图中清晰地显示了从几米到几百米深度范围内的地层结构和构造特征。通过对这些叠加时间剖面的分析,获得了不同激发震源、不同道间距、不同观测系统参数时间剖面的分辨率。给出了对于不同的探测目标层埋深和精度要求所适用的探测方法和工作参数,为提高断层探测的分辨率和活动断层最新活动时代的确定精度奠定了良好的基础。

| Abstract: | The high-resolution shallow seismic technique can be used for prospecting position, property and basic activity of a fault. We have obtained many high quality stack time sections by prospecting method with different seismic source, different geophone interval and different observing system on the Xiadian fault. These sections display clearly the stratum structure and the structure characteristics in the scale from several meters to several hundred meters. The prospecting methods and parameters fitting for g... |
