摘　　要：文章通过对某工程桩基静载、低应变法桩身完整性动测试验的实例分析,对检测出的不合格桩基采取工程措施进行了处理,对单桩竖向极限承载力的确定过程中的注意点等问题进行了探讨。文章指出风化岩作为桩基持力层时桩长控制的注意点,静载荷试验桩抽取原则。强调应重视地方桩基参数应用,有效运用静载荷试验和钻孔数据,今后应进一步讨论和研究土性的不确定性对桩基承载力的可靠性影响。Based on the analysis of the static load and low strain dynamic test of pile integrity in a project, the engineering measures for the unqualified piles found by the test are dealt with, and the points for attention in the determination of the vertical ultimate bearing capacity of single pile are discussed. It is pointed out that when weathered rock is used as bearing stratum of pile foundation, attention should be paid to the control of pile length in the principle of static load test pile extraction. It is emphasized that attention should be paid to the application of local pile foundation parameters, effective load test and borehole data. In the future, the influence of soil uncertainty on the reliability of pile bearing capacity should be further discussed and studied.
