TEST STUDY OF DX PILES WITH SINGLE AND DOUBLE BULBS AT TANG SHAN HTW ELECTRIC 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单节和两节DX挤扩灌注桩的极限承载力进行判定,并分析其荷载传递机理,对这两种桩的侧阻力和端阻力的分配及其发展规律进行研究。Abstract: Static loading tests for DX piles single and double bulbs which installed in fine sand conducted in field. The ultimate bearing capacities is 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 these two kinds are studied .
