摘要
介绍了低应变动测法的基本原理,结合钻孔灌注桩的低应变检测法,结合工程中常见的缺陷桩,分析了实际检测工作中典型的缺陷桩的低应变反射波曲线。通过对钻孔灌注桩的缺陷桩的处理,桩身完整性得到了明显的改善和提高,对类似工程将有一定的借鉴作用。
This paper briefly introduces the basic principle of low strain dynamic testing method. Combining with the bored grouting pile, this paper also introduces common defec tive pile in construction and analyzes low strain reflected wave curve of the typical defective pile in the actual testing work in detail. Through the treatment of the defective pile offor similar project.
