摘　　要：地震折射波法勘探受场地制约条件少、抗干扰能力强,是工程地质勘察的主要手段。以风机基础勘察为例,选用地震折射波法划分岩体风化程度和厚度。野外采集数据经预处理后,选用t0差数时距曲线法解释后的成果与钻孔资料基本吻合,为风机基础设计提供良好的设计依据。Seismic refraction survey is the main means of engineering geological survey because of its less site constraints and strong anti-interference ability.Taking the investigation of fan foundation as an example,this paper selects the shallow seismic refraction method to divide the weathering degree and thickness of bedrock.After preprocessing the field collected data,the interpretation results of t0 difference time distance curve method are completely consistent with the data of boreholes and exploration wells,which provides a good physical basis for the basic design of fan.
