摘要

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 corro-sion 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 an-chorage structure under composite factors properly. The device is feasible.%目的探究自行设计研究锚固结构电化学模型的可行性.方法针对通用电解池存在的缺点,自行设计电解池,模拟岩土工程中锚固结构综合受应力腐蚀和电化学腐蚀的环境,使锚固结构沉浸在1.0%NaCl溶液中进行腐蚀,并通过电化学方法进行检测,通过比较设计电解池与实验室电解池的测试结果,验证设计电解池的可行性.结果实验室模型和设计模型的实验结果相似性很高.结论所设计的电化学模型能够很好地研究锚固结构在综合因素作用下的腐蚀规律,装置是可行的.
