摘要
通过对楼层施工中大直径人工挖孔嵌岩桩的桩顶沉降、桩身应力和桩端阻的同步观测,提供了该型桩新的实测资料,分析了其在工作状态下的承载性状,包括桩顶沉降,桩端阻和桩侧阻分配与发挥,嵌岩深度和扩大头对桩侧阻和端阻的影响等。
Through simultaneous observation of pile-cap settlement,pile-end resistance and axial stress distribution in large-diameter rock-socket pile under multi-storied building construction,some new practical testing data are presented. Based on these data,the characteristics are analyzed of large-diameter rock-socket pile in working conditions,including pile cap settlement,distribution and exertion of pile-skin and pile-end resistance,selection of rock-socket depth,and the effect of pile end enlargement on pile-skin resistance and pile-end resistance.
