Abstract

This paper describes a quantitative evaluation of increase in horizontal effective stress of ground improved by Sand Compaction Pile (SCP) method, based on data obtained from the laboratory experiments. In the current practice, both vibratory and non-vibratory SCP used to improve loose sandy soil against liquefaction. In the research reported here, both methods of improvement imposed on laboratory samples. The process of installation was simulated in the laboratory by carrying out cyclic shear triaxial test and hollow cylindrical tortional shear test. Results indicated that the strength of ground to resist liquefaction, increases with coefficient of lateral pressure (K value), hence effect of ground improved by SCP in boosting K values can be regarded as one factor behind the strength of such grounds in resisting liquefaction.
