摘　　要：针对单桩竖向抗压静载试验和单桩竖向抗拔静载试验2种特殊工况,讨论分析经济合理地验算桩身强度和裂缝的计算方法,根据静载桩的实际受力状态对规范所给出的桩身强度验算公式做出修正与补充,并结合工程实例进行分析。In this paper,under the two special working conditions of single pile vertical compressive load test and single pile vertical pull-out load test,the calculation method of how to check the strength and crack of pile economically and reasonably is discussed and analyzed.At last,according to the actual stress state of load pile,to the pile strength checking formula given in the standard,the corresponding correction and supplement are made.Combined with the engineering example,the analysis is carried out.

关 键 词：静载试验 桩身强度验算 裂缝验算 抗拔检测 非预应力桩
