Objective To explore the feasibility of electrochemical model in researching the anchorage structure. Methods Electrolytic cell was designed based on its weakness to simulate the comprehensive stress corrosion and electrochemical corrosion environment of the anchorage structure in geotechnical engineering. The anchorage structure was immersed in 1.0 % NaCl solution for corrosion and tested by electrochemical method. The feasibility of the electrolytic cell was verified by comparing test results of designed electrolytic cell and laboratory electrolytic cell. Results The experiment results of laboratory model and design model had very high similarity. Conclusion The electrochemistry model designed can research the corrosion law of anchorage structure under composite factors properly. The device is feasible.
