Research on key technology of cement mixing plie on clay layer with high plasticity index

Abstract

Cement mixing pile is one of the common methods for road embankment foundation reinforcement, which can improve the bearing capacity, reduce the post-construction settlement caused by embankment loading, and increase the overall stability of embankment. In this paper, through field tests, lab tests and theoretical analysis, the factors affecting the quality of cement mixing piles in deep high plasticity clay soil are analyzed and the results of field tests and lab tests are compared, and finally the key construction parameters and relevant pile strength data in deep marine clay soil area are derived for similar projects.
