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。
After the 5.12 earthquake, using SIR-20 GPR to carry out non-destructive testing on the roadbed of Longshan-Slope section of Southwest University of Science and Technology and analyzing the data, the geological structure of the post-earthquake slope section was obtained: the road surface ruptured in many places and the roadbed subsidence , The existence of road and subgrade empty phenomenon, indicating that by the earthquake, there is a hidden disaster in this section. Relevant information and results can provide the basis for post-disaster reconstruction.
