Mutual Verification Case Analysis and Progress on the Pile Integrity Test Method

声波透射法、低应变法、高应变法和钻芯法是基桩完整性检测常用的方法。本文简述四种检测方法的工作原理,结合多种检测方法在基桩完整性检测中相互验证的实例分析,体现多种方法检测、综合评价的优越性和必要性,并对基桩完整性检测方法新的进展和趋势进行阐述和展望。

Pile integrity test includes acoustic transmission method, low-strain method, high-strain method and core drilling method. The working principle of the above detection methods are described in this paper. Combined with case analysis of a variety of detection methods to verify each other in pile integrity test, reflects the advantages and the necessity of detecting with a variety of methods, and a comprehensive evaluation. This paper also describes and discusses the new developments and trends of pile integrity detection.
