【摘要】 为了提高对混凝土裂缝检测的能力,引进在工程物探中应用广泛的叠加偏移成像技术。阐述了原理,借鉴地震勘探数据处理方式,根据弹性波在混凝土中的传播特性以及混凝土损伤检测的特点,制定出一套适合识别预制混凝土梁损伤的叠加偏移成像数据处理流程,从而得到对缺陷的成像。为无损检测技术人员定性、定量分析混凝土缺陷提供了实践和理论参考。更多还原

【Abstract】 In order to improve the detection ability of concrete,stack migration imaging technology widely used in geophysics has been recommended.Data processing flow of stack migration imaging of pre-damage concrete beam was presented on the basis of the principle and the seismic prospecting data handling styles,propertied of elastic wave propagation in concrete material and inherent characteristic of concrete damage detecting.Accordingly,the imaging of the damage dimension and location could be obtained.It could provide practice and theory reference of quantitative and quantificational analysis of concrete damage for nondestructive testing technology persons.更多还原
