摘　　要：通过 3 12国道六安—叶集段西汲河大桥钻孔灌注桩的静载荷试验 ,对该地区的软质岩石力学特性进行了综合分析 ,认为坐落在软质岩石上的桩基属于摩擦—端承桩类型 ,以桩尖承载力和桩周摩阻力共同作用 ,桩周摩阻力可取4 10kPa。Based on the static load tests on the bored cast-in-situ piles of Xijihe Bridge located within Liu'an─Yeji section of national No.312 highway and through synthetic analysis of the mechanical properties of the soft rock of that district, it is considered that the pile foundation on soft rock is of friction-end bearing pile type. Under the co-actions of pile toe bearing capacity and circumferential friction, the circumferential friction may be taken as 410kPa.
