Experiment and Rsearch on Influence of Consolidation Ratio on Dynamic Characteristics of Expansive Soil

GAO Chun-hua,ZHANG Qing-wei(Department of Civil and Building Engineering,Anyang Normal University,Anyang 455000,China)  
On the basis of the uneven consolidated condition,the expansive soil is studied,the influences of different consolidation ratios on dynamic characteristics of expansive soil are considered.Through dynamic triaxial test,dynamic characteristics of 5%lime-treated expansive soil under 5selected consolidation ratios are studied,the impacts of various consolidation ratios on it are concluded.In the range of analyzed consolidation ratio,the dynamic modulus of lime-treated soil increases markedly as long as consolidation ratio and deviator stress increase.The damping ratio is influenced by consolidation ratio as well,but the impact on damping ratio is less than that on dynamic modulus.
