SIR-20型地质雷达在震后滑坡路面分析中的应用

Application of GPR on Analysing the Landslide Pavement after Earthquake

在5.12地震发生后,运用SIR-20型地质雷达对西南科技大学龙山到新区坡段路面路基进行无损检测并分析所得数据,得到震后坡段地质结构情况:该路段路面多处破裂,路基沉陷,存在路面与路基脱空现象,说明受地震影响,该路段存在隐藏灾害。相关资料及结果可为灾后重建提供依据。

The roadbase and pavement in the campus of the Southwest Universty of Science and Technology were affected by the 8-magnitude earthquake in 2008,and potential geological disasters still occurred,especially on the slope section from Mt.Long Shan athletic field to the New District.The non-destructive testing was conducted in this area by the GPR SIR-20 and the test data was sorted out and analyzed.Thus the Post earthquake geological structures in this section were obtained,which can provide a reliable and scientific foundation for restoration and reconstruction in the future.
