摘　　要：通过桩身完整性检测可发现混凝土灌注桩某些可能影响承载力或耐久性的缺陷,灌注桩的桩身可能的缺陷类别和出现形式较多,加之检测方法的特点和适用性的不同,往往会出现采用一种方法不能全面评判的情况。结合工程实例,介绍了如何综合运用多种检测方法合理判定灌注桩的桩身完整性,实践证明,工程中选用检测方法应该灵活搭配、互相验证,避免误判或漏判的发生,使灌注桩的完整性检测结果更加准确可靠。Some pile defects that may affeect bearing capacity or durability of concrete cast-in-stu pile can be detected through pile integrity testing.However,there may be various types and forms of defects in the pile body of cast-in-stu piles,and due to differences in the characteristics and applicability of pile integrity testing methods,it is often difficult to fully evaluate the pile integrity using a single method.Combined with engineering examples,according to the actual situation of the project.This paper introduces how to judge the pile integrity of the cast-in-place pile by using a varitety of testing methods.Practice has proved that the selection of testing method in engineering should.The pile integrity testing methods should be flexibly matched and mutually verified,to avoid misjudgment or omission,making the results of the cast-in-stu pile more accurate and reliable.
