摘　　要：针对《建筑桩基技术规范》(JGJ94-2008)个别条文规定表述不够清晰、可能产生歧义的情况,结合工程实践经验、相关规范条文理解和理论分析,在桩基上部箍筋加密的应用场景、嵌岩桩岩体完整性评价、负摩阻力计算和公式调整等方面提出新的见解,并结合工程实际进行应用。In view of the unclear expression and possible ambiguity of some provisions in JGJ94-2008 technical code for building pile foundations,combined with engineering practical experience,understanding and theoretical analysis of relevant code provisions,this paper puts forward new opinions on the application status of stirrup densification on the upper part of pile foundation,rock mass integrity evaluation of socketed pile,calculation of negative skin friction and formula adjustment,and applies them in combination with engineering practice.

关 键 词：负摩阻力 饱和抗压强度 箍筋加密范围 岩体完整程度岩石质量指标(RQD)
