Study on dynamical modulus and damping ratio of lime-treated soil

摘要

In order to study dynamic properties of lime-treated expansive clay, a comprehensive series of laboratory tests were conducted via dynamic triaxial test system. The influences of factors such as moisture content, confining pressure, vibration frequency, consolidation ratio and the number of cycles on dynamic characteristics were discussed. It is found that the dynamic stress-strain curves of lime-treated expansive clay show the general trend of hyperbola. Compared with the remoulded expansive soil, the bearing capacity of lime improved expansive soil is higher than remolded soil.
