本文通过兰州中川民用机场扩建工程，采用地震映象和瞬态面波新技术，探查出形状各异、深浅多变、分布规律的１１８个不良地质体。文中认为采用常规工程勘察与工程物探新技术相结合的多种勘察手段，相互配合、相互补充、相互验证的综合探测方法，才能避免漏探，以获得最佳勘察效果。 In this paper, through the expansion project of Zhongchuan civilian airport in Lanzhou, 118 seismic geological bodies with different shapes, varying shades and distributions are explored by seismic mapping and transient surface wave technology. The article believes that by using a combination of conventional engineering exploration and geophysical exploration geophysical prospecting techniques, mutual cooperation, mutual complementarity and mutual verification of comprehensive exploration methods can avoid missed exploration in order to obtain the best prospecting results.
