Through the dry and wet cycling experiment on unmarred beam and pre - cracked beam , the position of initial corrosion and influence of crack on the reinforcing bar corrosion are studied in this paper both the flexural bearing capacity performance and the material mechanical performance of the beams are studied on the test of full scale concrete beam a model of 3d fem is established to simulate the state of the actual full - sized rc beam and electronic accelerating test beams , computational results and test results are compared 通過對混凝土梁的干濕循環試驗,研究了在混凝土梁中的鋼筋初始銹蝕情況,以及不同寬度的裂縫對于鋼筋初始銹蝕的影響。通過對足尺銹蝕混凝土梁的試驗,研究了混凝土梁在海洋環境侵蝕作用下的材料性能的變化和抗彎承載能力的變化。
