前言浅层折射波地震勘探是目前水文工程地质勘察中常用的物探方法之一,主要用来确定层状地质体的埋深和厚度,以及断层、洞穴的位置等。它的理论依据是:当下层介质的波速大于其上覆介质的波速时,在波射线的入射角大于(或等于)临界角的情况下,速度界面上会 Foreword The superficial refracted wave seismic exploration is one of the most commonly used geophysical methods in hydrological engineering geological prospecting. It is mainly used to determine the depth and thickness of layered geologic bodies and the location of faults and caves. Its theoretical basis is that when the wave velocity of the lower medium is greater than the wave velocity of its overlying medium, when the incident angle of the wave ray is greater than (or equal to) the critical angle, the velocity interface
