摘　　要：根据应用浅层地震在广州某高架桥地基的勘察结果 ,阐述了浅层地震在隐伏岩溶区勘察溶洞和溶蚀带的工作参数选取技术 ,并讨论了提高地震勘探效果及地震分辨率的技术措施 ,分析了对地震时间剖面进行地质解释的技术。Based on the investigation results obtained by shallow seismic method for the foundation of viaduct in Guangzhou,the selection of parameters for detecting karst and corrosion zone is expounded.The technical measures for improving effects of seismic exploration and seismic resolution ration are discussed and the means for the geological interpretation of seismic time profiles are analyzed.
