摘要
针对填方土体会逐渐产生自重固结沉降的现象进行了分析,探讨了填土负摩阻力对嵌岩桩竖向承载力的影响,并根据JG J 94-2008建筑桩基技术规范,指出验算单桩承载力时应考虑桩周土的负摩阻力引起的下拉荷载。
The paper analyzes the deadweight consolidation settlement caused by the addition of the earth fill,explores the influence of the negative skin friction of earth fill on vertical loading capacity of rock-socketed piles,and points out the downward loading caused by the negative skin friction of the surrounding pile of piles in the calculation of the single loading capacity of the piles according to the regulation of JGJ 94-2008 Architectural Pile Foundation Technique.
