摘　　要：根据竖向受荷时桩-土体系的荷载传递规律,在荷载传递法的基础上,利用功能互等定律推导出一套单桩承载力的计算公式.结合郓城水岸新都住宅小区桩基工程的单桩承载力计算,将计算所得Q-S曲线与现场静荷载试验实测数据所得Q-S曲线进行对比,证明该算法简单实用,可以很好地反演现场静载试验,且能保证计算的合理性和可靠性,对工程实践有一定的借鉴和指导意义.According to vertical loaded pile-soil system load transfer law,based on the load transfer method,a formula about bearing capacity of single pile is derived by using reciprocal work theorem.Furthermore,the bearing capacity of single pile of foundation engineering in the residential area of Yuncheng Waterfront Xindu is calculated,then Q-S curves calculated are compared with the measured fitted by the field static load test.The results show the algorithm is simple and practical,can obtain a good inversion of field static load test,and can ensure the rationality and reliability of the calculations.It can provide the reference and guidance for engineering practice.

关 键 词：单桩承载力 功能互等定律 静荷载试验
