Abstract

Abstract: The construction quality of the cast-in-place reinforced concrete piles for the foundations of a large oil refinery in karst terrain was examined by both the low strain and high strain dynamic pile testing methods. The pile capacities were verified through static axial compression, uplift and horizontal tests on piles instrumented with rebar strain gages and soil pressure cells at the pile tips. The axial load distributions under each load increment were also analyzed.
