为了对浅表地层缺陷进行探测,本文将以往对材料特性的反演,扩展到对浅层地表空洞缺陷的反演,并采用遗传算法作为反演优化算法,在时域下建立路面结构动态反演的方法,并编制了动力反演程序.在对地表下既有空洞的情况进行正演模拟的基础上,对在不同工况下空洞位置和大小进行了模拟反演分析和工程试验分析.通过对理论数据和实测数据进行分析,验证了反演程序的合理性和有效性.结果表明：利用动力对浅层地表空洞缺陷（大小、位置等）探测具有一定的适用性,为检测浅层地表缺陷提供了新的技术路径.

In order to find the defects in shallow surface,the inversion of material properties was extended to the inversion of the empty defects in shallow surface;genetic algorithm was used as an optimization algorithm of the back calculation.The method was used to solve the dynamic respond of pavement in the time domain,and a dynamic inversion procedure was developed.These rules were used to inverse the cavities under different conditions of location and size of the inversion.The theoretical and measured data were analyzed to verify if the inversion procedure is reasonable and effective.The result shows the use of impulse loads on the shallow surface with cavity defects（size,location,etc.） has some applicability for the detection of defects under the roadbed.It provides a new technology path to defect cavity defects in the shallow surface.
