工程桩基不同检测方法的检测结果比较

Comparison of the result between low strain integrity testing and core drilling method

根据低应变反射波原理,分析了桩身完整性检测结果的影响因素。结合某工程桩基采用反射波法和钻芯法进行同时检测,通过对现场检测结果的比较,讨论了反射波法及钻芯法检测桩身完整性存在的问题与处理方法,为更准确地判定桩身质量提供一些借鉴。

On the basis of fundamental principles of low strain dynamic testing of piles, this paper analyzed on some factors which effect pile integrity. Based on the data of low strain dynamic test and in-situ core drilling sample examination, the quality and detecting methods of pile are discussed. Through the comparison of testing results, the existing problem of the two methods is put forward. This study is useful for quality testing of piles.
