New technology of rapid,nondestructive and comprehensive testing for operation highway subgrade disease

With the characteristics of low testing veracity rate, slow testing speed and im- pact seriously on highway traffic, current subgrade disease nondestructive testing methods are unfit for operation highway. To solve this problem, based on the testing theory of ground penetrating radar, high density resistivity method and rayleigh wave method, through equipment transformation and comprehensive processing platform compilation, new technology of rapid, nondestructive and comprehensive testing for operation highway subgrade disease is presented. The results show that through adopting ground penetrating radar with antenna coupling to air, changing the layout methods of electrode and geophone, rapid testing for subgrade disease can be realized. Based on complementarity in testing ob- ject and index, by the acquisition and process method of multi-sensor fusion, subgrade dis- ease comprehensive testing can be realized. Based on subgrade disease comprehensive pro- cessing platform, combined interpretation of subgrade disease testing dates, visualization and gridding of subgrade disease can be realized. The application of new technology of rap-id, nondestructive and comprehensive testing for operation highway subgrade disease can im- prove the precision and efficiency testing, meanwhile nondestructive testing and maintenance technology for subgrade disease can be greatly promoted.
