摘　　要：开展了不同应力状态下钢筋混凝土梁电解液加速腐蚀试验,研究了加速腐蚀试验中通电时间、钢筋腐蚀率和荷载水平等外界条件对试验构件力学性能的影响,分析了钢筋锈蚀过程中梁截面应变变化和锈蚀裂缝产生情况,为进一步开展应力状态下钢筋混凝土梁的研究提供了试验参考。This paper presents results and discussions on an experimental study conducted to relate the influence of external conditions, such as the corrosion rate, the conduction time and the level of sustained load, on the mechanical properties of the corrosive beams under stress states that corroded by electrolyte accelerated corrosion test method. The strain for the cross section and the cracking development of corroded beams in the process of reinforcement corrosion are analyzed to provide a reference for further study of reinforced concrete beams supporting varied loads.
