摘　　要：地球物理勘查是河堤等工程设施隐患检查不可缺少的一个方法,能有效预防自然灾害和施工质量导致的河堤毁坏等问题,同时具有成本低、施工效率高的特点。都江堰水利工程飞沙堰河堤表面为水泥层,水流湍急,长年对河堤进行冲刷,限制了常规的地球物理勘查方法。文章综合考虑研究区的实际地质条件,选择GSSI地质雷达对飞沙堰提防隐患进行探测。通过对飞沙堰隐患段进行物探数据采集,结合地质资料综合分析,解译了飞沙堰堤防地段存在的隐患,为都江堰飞沙堰河堤隐患治理提供了必要的依据。Geophysical exploration is an indispensable method to inspect the hidden dangers of river embankment and other engineering facilities,which can effectively prevent the damage of river embankment caused by natural disasters and construction quality,and has the characteristics of low cost and high construction efficiency.The surface layer of Feisha dam is cement layer,and the current is fast,which limits the conventional geophysical exploration method.In this paper,considering the actual geological conditions of the study area,GSSI geological radar is selected to detect the hidden danger of Feisha weir.Through geophysical data collection and comprehensive analysis of geological data,this paper interprets the hidden danger in the section of Feisha weir,and provides the necessary basis for the hidden danger treatment of Feisha weir.
