摘　　要：以阜宁原状土为研究对象,对不同深度的土样,分别进行密度、含水率,以及无侧限抗压强度试验和压缩试验。试验结果表明:在阜宁取土区,浅层土偏向于粉砂,深层土偏向于淤泥质黏土,浅层土的无侧限抗压强度要远高于深层土,并且5 m以下原状土的无侧限抗压强度变化幅度不大,6 m深度附近原状土含水率最高、密度最小且具有更大的压缩性。以期为淮河入海水道二期工程“深软土段”加固方案提供数据支撑。In this paper,taking the undisturbed soil in Fu'ning as the research object,density and moisture content as well as unconfined compressive strength test and compression test are carried out on soil samples at different depths.The test results show that the shallow soil in Fu'ning soil sampling area tends to be silt,and the deep soil tends to be muddy clay.The unconfined compressive strength of the shallow soil is much higher than that of the deep soil,and the unconfined compressive strength of undisturbed soil below 5 m has little change.The undisturbed soil near the depth of 6m has the largest moisture content,the smallest density,and greater compressibility.It is ex-pected to provide data support for the"deep soft soil section"reinforcement plan of the second phase of the Huaihe River Water Channel Project.
