Abstract: It is pointed out that using the compactness as the only standard in testing quality of packing embankment is insufficient,and the influence of moisture on subsidence of embankment is analyzed in this paper. Based on the theory of general suction and general effective stress of remolding non-saturated soil,the mechanism of embankment subsidence is analyzed,and a theory of two-step settlement is presented.

Key words: moisture, subsidence of embankment, non-saturated soil, general suction, general effective stress, two-step settlement

摘要： 本文指出路堤填筑质量检测中压实度单一标准的不足，分析含水量对路堤沉降的影响．并从重塑非饱和土广 义吸力和广义有效应力原理出发对路堤沉降机理进行分析，提出进行二阶段沉降分析的观点
