摘　　要：文主要利用地震波在波速随深度呈线性增加的介质中传播这一理论，研究随深度增加而风化程度减弱的地表层以及地表常速 层和深部常速层，并且指出了这种方法与传统时距曲线法的区别．该方法在野外勘探中配合钻探和电子计算机的解释更能显示其有效性．In this paper, by the theory that seismic wave tyansmits in the medium in which wave velocity characterizes linear enhancement with the multiplying of depth, the surface layer whose weathering intensity wanes with multiplying of the depth, the surface normal velocity layer, and the depth normal velocity layer are studied. Moreover, the distinction between the way using the theory and conventional T-D curve method is pointed out. Actually, the combination of the way with the drill data and the data interpreted by computer in field survey is much more effective.
