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.It is pointed out that using the compactness asthe only standani 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 theoryof general suction and general effective stress of remolding non-saturated soil, the mechanism of enbankment subsidence is analyzed, and a theory of two-step settlement is presented.
