摘要
通过对泥岩路基材料在不同含水率不同压实度条件下的剪切实验研究,获得了不同条件下泥岩填料抗剪指标变化规律。结果表明:压实度相同条件下,泥岩填料粘聚力和内摩擦角均随含水率的增加呈现持续减小趋势;含水率相同条件下,泥岩填料粘聚力随压实度增大而增大,但内摩擦角基本保持不变。同时,基于实验数据对不同条件下的泥岩路基填料的变化规律进行拟合分析,进一步获得了不同条件下泥岩填料抗剪性能变化规律。
Through the shear experimental study of mudstone subgrade materials under different water content and different compaction,the mudstone fillers change rules of shear resistance index under different conditions was obtained.The results show that under the same compaction degree,the cohesion and internal friction angle of mudstone filler decrease continuously with the increase of water content;under the same water content,the cohesion of mudstone filler increases with the increase of its compactness,but the internal friction angle basically remains unchanged.At the same time,based on the experimental da-ta,the change rule of mudstone subgrade filler under different conditions was fitted and analyzed,and the change rule of shear resistance of mudstone filler under different conditions was further obtained.
