摘　　要：结合安徽某综合写字楼项目,在计算PHC管桩的竖向极限承载力标准值时分别采用了经验参数法和静力触探法,并把两种估算结果与单桩静力载荷试验报告数据进行了对比,对比结果表明:本项目用静力触探法估算单桩极限承载力更加接近试验值。通过对比说明静力触探法在不断积累经验后,在本地区地质类型相似的项目是可以推广应用的。This article combines a comprehensive office building project in Anhui to calculate the standard value of the vertical ultimate bearing capacity of PHC pipe piles by using the empirical parameter method and the static cone sounding method respectively,and combines the two estimation results with the single pile static load test report data A comparison was made,and the comparison results show that the ultimate bearing capacity of a single pile estimated by the static cone sounding method in this project is closer to the test value.Through comparison,it is shown that the static cone sounding method can be promoted and applied in projects with similar geological types in this region after continuous accumulation of experience.
