摘　　要：基于地震映像法,分别利用纵波和横波作为有效波,对机场道面结构脱空状态进行检测识别。通过ABAQUS有限元软件建立了机场道面结构的二维有限元模型,数值分析了纵波和横波在机场道面结构中的传播规律,验证了纵波地震映像法和横波地震映像法对脱空道面检测识别的可行性。Based on the seismic imaging method,P-wave and S-wave are used as effective waves to detect and identify the void state of the airport pavement structure.By establishing a two-dimensional finite element model of the airport pavement structure using ABAQUS,the propagation law of P-wave and S-wave in airport pavement structure is analyzed,and the feasibility of using P-wave seismic imaging and S-wave seismic imaging to detect void of airport pavement structure is verified.
