Study on the behavior of model piles embeded in sand and subjected to static and cyclic lateral loadings

الملخص EN

Testing of model piles in the laboratory can be used to predict the behavior of laterally loaded piles by maintaining field conditions to the maximum extent.

Model piles with different diameters which were embeded in medium density sand have been tested under dry and submerged conditions and subjected to lateral static and cyclic loadings.

A description of the test arrangement and the loading system for the model piles is presented along with a study of the effect of important parameters which affect the behavior of laterally loaded piles.

The bending moment along the pile length, pile deflection and soil resistance have been studied as affected by these important parameters.

Experimental resistance-deflection (p-y) curves have been obtained and compared with the semi-empirical p-y curves.

The semi-empirical p-y curves overestimate the lateral soil resistance leading to a smaller design moment which could cause unsafe pile design.
