摘要

Knowing the lateral load-carrying capacity of a pile is essential to assess its ability to resist static and dynamic horizontal forces, usually verified through an in-situ load test. Using actual field soil stratification and laboratory-tested soil properties to attain a permissible deflection of 5 mm, this paper aims to validate the lateral deflection at the pile top against the calculated lateral load capacity of a 1000-mm diameter, 25-m-long free-head cast-in-situ pile of M35 grade concrete in cohesionless soil. Real in-situ load-deflection results from a lateral pile load test, conducted according to the current Indian Standard code of practice, are compared with those from the finite difference method-based Ensoft L-Pile software and the finite element method-based PLAXIS 3D software in reference to its MC, HS, and HSS models.
