摘　　要：河堤水闸存在土体松散、塌陷、空洞等病害时,若无法及时发现,后续发生破坏,会严重威胁当地群众的生命和财产安全。地质雷达方法具有连续、无损、高效和高精度等优点被广泛应用于公路路基病害诊断方面。本文将地质雷达应用于佛山市顺德区龙江镇歌滘水闸安全鉴定中。在地质雷达数据成像剖面上,因土体松散土体松散、塌陷、空洞与围岩有明显的介电常数差异,呈现出来的是圆弧状的多次强反射界面,证明地质雷达方法在河堤水闸安全鉴定中有较好的应用效果。When there are soil loose,collapse,cavity and other diseases in the river bank sluice,if it cannot be found in time,the subsequent damage will seriously threaten the life and property safety of the local people。The geological radar method has been widely used in the diagnosis of roadbed diseases because of its advantages of continuous,non-destructive,high efficiency and high precision。This paper applies geological radar to safety appraisal of Gejiao sluice in Longjiang Town,Shunde District,Foshan city。In terms of geological radar data imaging section,due to the soil loose,loose soil subsidence,empty and has the obvious difference of dielectric constant and surrounding rock,presented the arc shape of strong reflection interfaces for many times,show that geological radar method this method is effective in the embankment safety appraisal of sluices have good application effect。
