【摘要】 通过现场静荷载试验,对以稍密粉砂、中密粉砂和中密粉细砂为承力盘持力层和以中密粉细砂为桩端持力层的四节DX挤扩灌注桩的极限承载力进行判定,分析桩的荷载传递机理,并对桩侧阻力、盘端阻力和桩端阻力的分配及其发展规律进行研究,最后对DX桩在WW大厦的应用情况给予介绍。更多还原

【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.更多还原
