Abstract
The field prototype tests have been carries out for under-reamed piles bearing uplift loading in the loess of droughty area. In these tests, uplift displacement and horizontal displacement of under-reamed piles bearing uplift loading and horizontal loading, displacement of surface layer soil, relationship of loading and displacement were measured. The ultimate uplift bearing capacity, failure mechanism of piles were studied. It is very effective on improving ultimate uplift bearing capacity of pile to raise height of belled-out section of under-reamed piles. Strength failure mechanism of pile and soil is solved by gradually failure to be due to damage softening and reduction pressure softening of the soil. A theoretical model has been proposed to calculate the ultimate uplift bearing capacity in the loess, and comparing the calculation results with the test data, both are basically similar, which shows to have chosen correct calculation pattern.
