摘要
旋挖钻孔灌注桩和泥浆护壁钻孔灌注桩是近年来黄土地基中广泛使用的桩基形式。本文通过黄土地基中旋挖钻孔灌注长桩和泥浆护壁钻孔灌注长桩静载荷试验和桩身应力的测试,分析了黄土地基中两种成孔工艺钻孔灌注长桩桩身轴力的传递规律、桩侧阻力及桩端阻力的发挥性状,探讨了两种成孔工艺对钻孔灌注长桩承载力的影响。
The bored pile by churning drive and bored pile with slurry wall protection are widely adopted in loess foundation in recent years. Based on the results of vertical static loading test and stress test for longhole bored pile in loess foundation, by analysing the transferring law of axial force and the action of lateral friction resistance and bottom resistance, the paper discusses the influences of two types of holing technology on bearing capacity behavior.
