Abstract：In recent years,with the rapid development of highway construction,the safety and durability of bridge-heads,as an important part of expressways,have been paid more and more attention.However,it is inevitable that various diseases occur during the use of bridgehead.In order to explore a new method of disease detection at the bridgehead,the three-dimensional radar detection method was applied and a three-dimensional radar detection vehicle was used to detect a highway bridge in Guangdong Province.According to the classification of the disease of bridge-head,such as disengaging,loose and subsidence,the distribution,depth,location and area of the diseases in the bridge head and inside of the bridge head were analyzed.Combined with the on-site investigation and coring verifica-tion,the inside of the endoscope was viewed.Finally,the results obtained from radar scanning and the endoscope were consistent,and the feasibility and accuracy of three-dimensional radar detection were analyzed.
