摘要
许多高层建筑、大型桥梁、码头等工程采用嵌岩桩,其以承载力高、沉降小、群桩效应弱的特点,极好地满足了高、重、大型建筑物对基础的特殊要求。因软岩具有"非土非岩"的特点,现行规范中给出的嵌岩桩计算方法过分保守,与实际工程不符。文章讨论了《建筑桩基技术规范》[1]中软岩嵌岩桩单桩承载力计算出现的问题。
Many engineering structures such as high-rise buildings, large-scale bridges, and docks adopted piles embedded in rock, which is characteristic of high capacity, small settlement and weak group effect, and can meet the particular requirements of high, heavy and massive constructions very well. Because soft rock has a particular engineering quality, not soil or not rock, the method for evaluating the end bearing capacity is too conservative and is not consistent with the fact. The paper discusses the issues in Technical Code for Building Pile Foundations when calculating the end bearing capacity of piles embedded in soft rock.
