摘　　要：结合伊洛河河滩相软土地基上修筑1km多长的高等级公路路堤实际工程,设计软土地基变形现场观测方案,采用测斜导管、沉降板等测试方法,对软土地基变形进行长达2年多的观测研究,共获取数据2万多个。通过对这些数据的分析,结合河滩相软土特点,提出软土地基路堤施工控制的最薄弱层法和预压期控制方法。By using inclinometer tubes and settlement plats,test project of soft clay base was designed and observation has been lasting more than two years in a more than one kilometer highway which was built on the YiLuo River alluvial flat soft day base in Henan province.As a result,more than twenty thousand data were obtained.By analyzing these data and the characteristic of alluvial flat soft clay,the methods that control embankment construction and precompression are brought forward.
