摘要: 以物探大队在郑州、天津、内蒙等地进行工程勘察时的浅层地震勘探资料为实例,阐述浅层地震反射法在黄泛洪、冲积区和流动沙丘等地区进行工程勘察时的方法特点及应用效果。结果表明,浅层地震反射法在岩层划分、探测覆盖层厚度及断层勘察等方面有独到作用,可为工程的设计和建设提供准确可靠的地质依据。Abstract: This paper takes the shallow seismic prospecting data of our institute in Zhengzhou, Tianjin and Inner Mongolia as examples to illustrate the characteristics and effect of this reflection method for engineering survey in Yellow River proluvial and alluvial regions and wandering dunes regions.The results show that this method is very useful for layer division, determination of the thickness of sediments and faults.It can afford reliable geological data for engineering design and construction.
