通过卫星影像资料和地质资料,结合浅层地震勘探结果,对滦县县城附近的响堂断裂、坨子头断裂以及唐山断裂进行初步研究,确定3条断裂的活动性质及产状。研究表明滦县县城附近第四系埋深在70~120m范围内,3条目标断裂都错断了第四系底界,断层上断点位于第四系地层中。
Combined with satellite images,geological data and seismic exploration results,the nature of fault activity and fault occurrence of Xiangtang fault,Tuozitou fault and Tangshan fault were determined.The results show that the Quaternary depth is from 70to 120mnearby the Luanxian County,the bottom boundary of the Quaternary strata was faulted by the three target faults,the upper breakpoint of the fault located in the Quaternary strata.
