Application of Ground Penetrating Radar in the Detection of Offshore Structures at Beach

According to the principle of GPR and the structural characteristics of offshore structures at beach, this paper analyzes the feasibility of applying GPR to the detection of offshore structures at beach, and introduces the application effect of GPR with engineering examples. The engineering examples show that GPR can be well used to detect the engineering quality and internal hidden defect detection of offshore structures at beach, provide detection means for daily safety detection and quality evaluation of maintenance and reinforcement of offshore structures at beach in intertidal areas, and has reference value for the detection and maintenance of seawall and breakwater structures in non-intertidal areas.
