摘　　要：西南科技大学老校区某处边坡处在特殊的地质环境中,存在潜在的滑坡危害。为了给其安全防治工作提供有效的科学依据,采用SIR-20型地质雷达进行了无损检测并分析所得数据,发现坡体原始结构层均遭受了一定的破坏,存在多处裂缝,坡体内存有积水,影响了其地层结构的稳定性,遇雨水长期浸润,极易出现整体滑坡现象。根据检测结果提出了相应的排水沟网和抗滑桩支挡的预警措施。A slope in the old campus of Southwest University of Science and Technology has a special geography and land features, which may cause a potential landslide. The data surveyed by non - destructive inspection of GPR SIR - 20 and sequent analysis show certain destructions, several cracks and waterlogging exist in the original stratum structure, which influences the stability of other stratum and indicates a possible landslide under condition of long - terra saturation. According to the analysis, several measures are provided such as drain ditch system and anchor anti - slide piles.
