摘　　要：结合镇江地区某工程的钻孔资料,开展不同深度土样的室内压缩试验,验证了考虑沉积作用土层初始有效应力计算方法的有效性。通过压缩试验成果验证镇江地区下蜀黄土大多处于正常固结状态,结合初始有效应力和初始孔隙比的确定方法,获得镇江下蜀黄土的原位压缩特性,给出其原位压缩曲线,为今后该地区下蜀黄土层的变形计算提供理论支撑。Combining with the drilling documents of some project in Zhenjiang Area,the paper undertakes the indoor compression tests on soil samples with different depths,proves the efficiency of the initial effective stress calculation methods with the consideration of the deposition,proves that most of Xiashu loess of the area is in normal consolidation,acquires the in-situ compression features of Xiashu loess by combining with the identification methods for the initial effective stress and initial void ratio,proves its in-situ compression curves,so as to provide the theoretic support for the deformation calculation of Xiashu loess layer of the area.
