| 摘 要： | 依托济南—乐陵高速公路路基勘察项目,依据试样的室内土工试验成果,应用回归分析方法,建立了黄河冲积平原低液限土的含水率与土的密度、孔隙比和压缩系数及土的塑性指标等相关经验公式;对区内赋存的低液限粉质黏土,通过与其他相近密实度的土,在抗剪强度及单向固结条件下固结特性的比较分析,指出该区域此类土质具有所谓的"高密度、低强度、中(偏高)压缩性"的工程特性。

| Abstract: | The authors established the related empirical formula about moister content and soil density, void ratio and compression coefficient as well as plasticity index of soil for low liquid limit clay of alluvial flat of Yellow River based on the indoor earthwork test results and with the help of regression analysis. Through contrast analysis of the consolidation characteristics under conditions of shear strength and one-dimensional consolidation for the low liquid limit clay in the study area, the authors concluded that the soil in the study area was characteristic of high density, low strength, moderate (high) compressibility |
