| 摘 要： | 利用高分辨率浅层地震方法对唐山断层进行精细探测，得到了300m以上尤其是近地表结构的清晰图像，证明NW倾向的唐山断层在活动时，南段是一个高角度的正断层，向上错断了全新统(Q4)；北段则表现出逆断层的性质。

| Abstract: | A detailed detection of the Tangshan fault was carried out byusing high-resolu tion shallow seismic sounding technigue. Distinct images of the fault structure above 300m depth and especially near the sueface were obtained through the detec tion. The results show that during the faulting process, the southern segment of the NW-dipping Tangshan fault appeared as a high-angle normal fault dissectin g the Holocene deposits, while the northern segment of the fault appeared as a r everse fault. This may indicate the segmentation of the activity of the Tangshan fault. |
