摘　　要：低应变发射波法可以为桩基检测提供有效的、非破坏性的评估手段,为桩基的设计和维护提供可靠的依据。本文从基本理论出发,讲述了低应变反射波法的基本原理与实际应用的意义,并结合工程实际分析了不同桩基情况下的低应变反射曲线的特征。通过分析低应变反射曲线的特征,可以对桩基问题进行初步判断,然后进一步采取适当的措施进行修复和维护。The low strain reflection wave method can offer an effective and non-destructive evaluation method for pile foundation test,and provide reliable basis for the design and maintenance of the pile foundation.This work starts from the basic theory and explains the fundamental principles and practical significance of the low strain reflection wave method,which also analyzes the characteristics of low strain reflection curves under different pile foundation conditions in combination with engineering practice.By analyzing the characteristics of low strain reflection curves,preliminary judgments can be made on pile foundation problems,and then appropriate measures can be taken for repair and maintenance.
