碎石垫层调整路基差异沉降的现场监测与分析

我国对水泥混凝土路面下碎石垫层的研究很不充分，对碎石垫层调整路基差异沉降的机理研究较少，缺乏对碎石垫层调整路基差异沉降的现场监测研究。依托广东省阳江～阳春高速公路进行了碎石垫层调整路基差异沉降的现场监测研究，研究成果对于完善水泥路面碎石垫层的设计方法具有重要作用。

Site Monitoring and Analysis on Differential Settlement of Subgrade Adjusted with Gravel Cushion

As there is not sufficient researches on the gravel cushion under cement concrete pavement in our country, there is less researches on mechanism of subgrade differential settlement adjusted by gravel cushion,there is also short-age of researches on on-site monitoring for subgrade differential settlement adjusted by gravel cushion.In this article, being based on practice of Yangjiang-Yangchun Expressway in Guangdong Province,study on on-site monitoring for subgrade differential settlement adjusted by gravel cushion has been carried out,and the study findings have an impor-tant role on the design method improvement for gravel cushion for cement pavement.
