The report on the work of GPR theory of subgrade response characteristics based on research carried out Subgrade signal processing,identification and display technology in the research,development of the disease database system,road pavement thickness evaluation systems.
The projects address the following key technologies:the establishment of a two-dimensional,three-dimensional digital model; established Subgrade processing,recognition algorithm; establishment of moisture content and porosity of the quantitative analysis model; a three-dimensional structure model shown.
