A Lateral-Load Test of a Full-Scale Pile Group in Sand.

Abstract

Lateral-load tests were performed on a large-scale, well-instrumented group of piles in sand. A similar single pile, also well-instrumented, was tested in the same soil. The group of piles and the single pile were installed in Houston for previous research projects. The native clay soil was removed from the upper portion of the piles and replaced with clean sand. Cyclic lateral loads were applied to the piles, and the response of the instrumentation was recorded. The results of the loads test of the group are compared with the results of current design methods. The methods include DEFPIG, the Focht-Koch method, the single-pile method, and the Bogard-Matlock method. Because none of the methods provided entirely satisfactory results, an analytical procedure is provided which yields good agreement with the results of the load-test.
