This research was undertaken to explore the interaction behavior of soil-pile systems subjected to static and dynamic lateral loads. The principal objective of the study was to assess the applicability and accuracy of one of the prominent methods of analysis by comparing the predicted responses with the measured responses.
Presented in this report is a brief survey of the related literature on the existing analysis techniques and previous experimental studies, the details of the experimental work performed under the current study, and the appraisal of the performance of a finite element program adopted for making theoretical predictions of the experimental responses.
In the present study, both static and dynamic experiments were conducted to obtain experimental data against which the analytical predictions could be verified. The experiments included laboratory simulation of the response of piles subjected to static or dynamic lateral loads applied at the pile-head and of piles embedded in a soil deposit subjected to bedrock motions. Finite element analyses of the model systems were carried out using reasonable estimates of the system parameters. No attempts were made to establish the model parameters through rigorous identification procedures.
It is shown that the agreement between the predicted and measured responses can be excellent even if the properties and parameters of the soil--pile system are only roughly estimated.
