摘要
应用瑞利波原理,分析沪宁高速公路瑞利波检测数据,通过钻孔取样验证瑞利波检测结果可靠性,拟合波速与压实度对应关系式,提出路基质量的瑞利波速评价标准,表明瑞利波波速确立了高速公路路基路面质量指标与检测物理参数间直接或相关关系。
This paper uses the principle of Rayleigh waves to analyze Rayleigh wave detection data of the expressway from Shanghai to Nanjing, verifies reliability testing results through the drill hole sampling, fits relationship between velocity and compactness, and proposes the Rayleigh wave speed evaluation criteria of foundation quality, which shows that Rayleigh wave speed determines the direct and relevant relationship of quality indexes of expressway foundation and subgrade with the physical testing parameters.
