【摘要】 通过对湿陷性黄土中的3根挤扩支盘桩进行预浸水静载荷试验。结果表明,支盘桩荷载-沉降曲线为缓变型,具有较好的承载性能,荷载传递规律与在非湿陷性黄土地基中具有相似的性质,桩身各段承载力的发挥具有明显的顺序性。试验结果为湿陷性黄土地基中支盘桩的应用提供了依据。更多还原

【Abstract】 Three squeezed branch piles are tested in collapsible loess foundation after prewetting processing.The results indicate that the load transfer law of squeezed branch pile is similar to that in the ordinary soil,the velocity of load-settlement curve changes slowly and the pile has high load bearing capacity,the principle of load transfer has apparently sequence.The results may provide a basis for the use of squeezed branch piles in collapsible loess foundation.更多还原
