摘要
Based on the results of indoor consolidation tests, the authors analyzed moisture content, porosity ratio, grain-size, compression modulus and Pc of the Yellow River soil, and concluded that the soil is in normal consolidation at 6 m depth, and above this critical depth the soil is over-consolidated while beneath it the soil is under-consolidated. The research also indicates that formation of the over-consolidation state is attributable to the influence of the cementation effect and sedimentary environment.yes"> And the difference in cementation and in impacted depths of the waves decided over-consolidation inhomogeneity at different depths.yes">
