TEST STUDY OF DX PILESWITH DOUBLE BULBS AT HENAN HMQ ELECTRIC POWER PLANT
-
摘要: 通过现场静荷载试验,对以粉细砂为承力盘和桩端持力层的两节DX挤扩灌注桩的极限承载力进行判定,分析其荷载传递机理,并对桩侧阻力、盘端阻力和桩端阻力的分配及发展规律进行研究。Abstract: Static loading tests for DX piles with double bulbs installed in silty fine sand were conducted in field.The ultimate bearing capacities are determined, its 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.
