【摘要】 对桩基完整性分析中遇到的有关问题进行了分析，指出目前反射波法只能对桩身波阻抗变化进行检测，无法区别桩身弹模及横截面积变化对反射波形的影响。完整性分析仅是对桩的评价一个依据，常用的分类方法有很多方面值得商榷。为了提高分析精度，对波形进行定量分析是很有必要的。更多还原

【Abstract】 The paper analyzes the related problems met in the analysis of pile foundation integrity and states that reflecting wave method can only detect the wave impedance change of pile body and can not differ from the influence of elastic membrane change and cross-section area change on the reflecting wave pattern. The integrity classification is a basis for evaluating the piles.Common classifications should be discussed in many aspects. In order to improve analytic precision. it is nessary to make quantitative analysis for wave pattern.更多还原
