摘　　要：介绍了低应变动测法的基本原理,结合工程实例介绍了桥梁工程中常见的缺陷桩,分析了典型缺陷桩的低应变反射波曲线,可在解释低应变反射波曲线和判别基桩缺陷性质时作为借鉴。This paper introduces the basic principle of low strain reflected wave method,and combined with project examples,introduces the common defective piles.The low strain reflected wave curves of the typical defective piles are analyzed,in order to explain the low strain reflected wave curve and discriminate the defect properties as a reference.

关 键 词：低应变反射波 缺陷桩 断桩 波形曲线
