Abstract

Based on the static loading tests on pretension high-strength concrete piles with stain gauges mounted at the top and toe of pile and at the interfaces of soil layer, the load transfer mechanism of PHC piles was studied, and the behaviors of skin resistance and toe resistance were analyzed. The relations of the jacking pressure of test piles to the embedded depth were measured.
