Abstract

Abstract

Static loading tests for DX piles with three and four bulbs installed in hard clay and stiff clay also for uniform bored pile installed in gravel sand were conducted in field. The ultimate bearing capacities are determined, and the load transfer mechanism is analysed, and the distribution and development of the skin-friction resistances, the bulb resistances and the tip resistances of DX piles of this kind are studied.
