Abstract
This paper presents the results of full-scale, field lateral load tests on four instrumented single piles installed in sand, and a comparison of predicted and measured lateral load-deflection response of single piles in sand. The pile load testing was conducted to verify the lateral load capacities of piles to be used to resist loads from various structures of a steam generated, power plant. The piles were installed in sand. The test site was prepared by removing the top stratum of cohesive soils and backfilling the test site with dredged sand, in order to simulate the site conditions expected during installation of piles to resist structural loads. The test results showed that the piles can adequately resists the lateral loads. Lateral load response of piles was predicted using a computer program LpilePlus which uses p-y curve method for the analysis of piles. The results presented show that the response prediction using p-y curve method is generally conservative.
