本文以两种不同类型的基桩(灌注桩、管桩)为例,简要介绍基桩低应变动测技术的基本理论,在两种不同类型基桩检测中的对比应用,以及如何判断灌注桩与管桩中存在的缺陷,从而达到控制基桩质量的目的,并能使低应变法得到更好的理解和应用。 In this paper, two different types of foundation piles (bored piles and pipe piles) are taken as examples to briefly introduce the basic theory of low-strain dynamic measuring technology of foundation piles and to compare the application of two different types of piles in testing and how to judge whether the bored piles And the existence of defects in the pipe pile, so as to achieve the purpose of controlling the quality of the pile, and can make the low strain method get a better understanding and application.
