公路路基填土的基本物理性质研究

Study on Basic Physical Properties of Roadbed Filling

依托内蒙G210线添漫梁北至越家壕(查干段)改线工程,通过开展颗粒分析试验、界限含水率试验以及标准击实试验,分析研究了该实际工程中两种填土土样的颗粒级配、塑性指数和最大干密度等基本物理性质,确定了土样的最优含水率和最大干密度。试验结果表明,两种填土土样级配均匀,液限和塑性指数满足规范要求。

This paper relies on the Inner Mongolia G210 line Tianmangbei to Yuejiatun(Chagan section)rerouting project,through the analysis of particle analysis test,boundary moisture content test and standard compaction test,the two kinds of fill in the actual project are analyzed and studied. The basic physical properties such as particle gradation,plasticity index and maximum dry density of soil samples determine the optimal moisture content and maximum dry density of soil samples. The test results show that the two fill soil samples are evenly graded,and the liquid limit and plasticity index meet the specification requirements.
