基桩完整性检测方法研究

Research on the Detection of Pile Integrity

基桩的完整性是检测桩基础是否合格的重要指标,有效的检测方法是查明桩身完整性的有力保障。桩身完整性的检测方法有多种,每种检测方法都有其独特性,并适用于不同的检测环境,因此,如何根据工程特点选择适合的检测方法是本文的研究重点。本文在对比了基桩桩身完整性检测方法的优缺点基础上,阐述了各种检测方法的使用条件,分析了桩周岩土性状对基桩完整性检测的影响情况,探讨了复杂地质条件下灌注桩完整性检测方法的选择和验证,为类似工程提供参考和借鉴。

The integrity of the pile is an important indicator to check whether the pile foundation is qualified, while effective detection methods are strong guarantee to ensure the integrity of the pile. There have many methods for detecting the integrity of piles body, each method has its own uniqueness and adaptation for different detection environments. Therefore, how to select suitable detection methods according to engineering characteristics is the research focus of the paper. In this paper, the advantages and disadvantages of the method for detecting the integrity of piles and its body are compared, the suitable conditions of using various test methods are expounded. On this basis, the influence of geotechnical properties around piles on the integrity of piles is analyzed,the selection and verification of the integrity test method for cast-in-place piles under complex geological conditions are discussed. The research provides reference for similar projects.
