反射波法(P.I.T.)在某营业楼桩基完整性测试中的应用

Applying of The Reflect Method (P. I. T.) At A Engineering Pile for Test of Pile Integrity

本文给出了该工程的基本情况及本次测试所采用的P．I．T桩基完整性测试仪基本性能，同时简要论述了反射波法的基本原理及典型曲线的判别规则。最后给出了该工程的部分实测曲线，重点论述了一种异常曲线的研判及开挖验证。

The general situation of the engineering project and the fundamental function of P. I. T. (pile integrity tester) adopted are described in this article. Fundamental Principle of reflect wave method, and distinguishing rule for typical curves are breifiy discussed. Finally, some of the measured curves of the project are given. Emphasis is laid on the study of abnormal curve and the check work done by in-situ excavation.
