摘　　要：以川西某工程为例,采用详实的现场调查、测绘,室内颗粒分析、抗压、抗剪、化学分析试验、室外标贯、动力触探、固体体积率、载荷试验、波速测试、颗粒分析、抽水试验等系统地研究了冰碛层工程性质,并结合工程实践采用强夯、碾压等方法对冰碛层地基进行了处理试验,并对挖方原地面地基和高填方地基进行了变形观测。结果表明,冰碛层总体为一种良好的地基和填料,可作为机场、公路、房屋等建筑地基。Based on engineering practice in one national key project, a comprehensive study on the engineering behavior of glacial till layer using various testing methods including filed investigation, survey, laboratory gradation analysis, compression test, shear test, chemical analyses test, standard penetration test, dynamic penetration, volumetric analysis, load test, wave velocity test, and well pumping test is reported. Ground treated with dynamic compaction and rolling compaction is observed with respect to the deformation of original ground and high fill embankment. Research results show that glacial till as natural ground and/or fill material can be used in the construction of airport, highways and building.
