| Abstract: | To study the characteristic and capacity of a new-style composite pile under lateral loads based on test results and discrete layer model of soil,the pile deformation,moment,shear and soil pressure around the pile were analyzed under lateral loads.The results indicate that inserting a core pile can modify stiffness and transfer way of the cement mixed pile and improve its side frictional resistance and lateral capacity.The composite pile has bigger lateral stiffness and lateral deformation is mainly distrib... |
