Abstract

Abstract

Static loading tests for DX piles with four bulbs installed in silty sand and silty fine sand were conducted in field. The ultimate bearing capacities are determined, 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. Finally, the values of the settlement measurement of WW Building are also listed.
- DX pile,
- bulb bearing,
- static loading test,
- ultimate bearing capacity,
- skin-friction resistance,
- bulb resistance,
- sand stratum
