【摘要】 本文主要是结合探地雷达的应用研究,拓宽探地雷达的应用范围和应用的有效性,可以高效、准确地发现高等级公路内部病害缺陷,为预防性养护工作提供有效的技术手段和解决方案。并针对出现的路基路面病害提出相应的预防性养护方案及措施,做到早预防、早治理。以达到根治病害,延长道路使用寿命的目的。以京沪高速公路为例,高填方路基段的路面出现了较多数量的纵向裂缝,以及路面沉陷、坑槽等典型病害,并且有越来越严重的发展趋势。利用先进手段,准确地判定这些高填方段路面病害产生的原因,分析病害的发展规律,找出根治这些病害的有效措施进行预防性养护,对于改善道路运营环境,降低运营成本将有着重要的现实意义。更多还原

【Abstract】 This paper mainly combines with ground-penetrating radar application,wides radar application scope and application of the validity , efficiently discovers accurate highway internal defects found defects, and provids effective technical means and solutions for preventive maintenance work. It raises corresponding preventive measures and conservation programs with appeared subgrade pavement distress,so we can achieve early preventing and control. Finally It can clear up radical diseases and extend the life of the road.High fill embankment of the road appears to more number of vertical cracks,road subsidence,pits and so on ,and this phenomenon becomes more and more serious as an example to the Beijing-Shanghai Expressway. We can exactly gauge the causes for the diseasethese of these high fill sections of the roads,analyze the development of thse diseases,search out effective measures to avoid these radical diseases and carry preventive maintenance out with the use of advanced means.It is an important practical significance for improving road operating environment and reducing operating costs.更多还原
