摘要
以广州机场高速基层注浆项目为依托,阐述了冲击映像法的原理、仪器设备、测线布设和数据的收集,介绍了冲击映像法在基层病害的检测和注浆效果评价方面的应用。检测结果表明,注浆后道路基层冲击响应能量显著降低,道路基层的均匀性得到改善,冲击映像法在道路病害检测方面有着广阔的应用前景。
Based on the high-speed base course grouting project of Guangzhou Airport,expounds the principle,equipment,line layout and data collection of impact imaging method,and introduces the application of impact imaging method in the detection of grassroots diseases and the evaluation of grouting effect. The test results show that the impact energy of the road base layer is significantly reduced after grouting, and the uniformity of the road base layer is improved. The impact mapping method has broad application prospects in road disease detection.
