【摘要】 本文深入探讨了嵌岩桩的荷载传递机理,对目前规范采用的嵌岩桩嵌岩深度计算方法进行了深入分析,针对规范方法没有考虑桩身转动时桩尖断面与基底岩接触面上产生的反力矩等有利条件的影响而导致最后的计算结果偏大的不足,提出了两种修正方法。最后还通过具体计算实例进行了分析验证。更多还原

【Abstract】 Loading transfer mechanism of rock-socketed pile is discussed.Then,calculation methods mentioned in the technical codes are analyzed.The insufficient is that the code methods doesn’t consider some useful effects,such as the moment on pile tip formed by pile rolling motion.Two modified calculation methods are proposed to make up this insufficient.Finally,an examples is employed to validate the method proposed in this paper.The calculation results show that the method is much feasibility.更多还原
