中文摘要：
选择常规截面，遵循二维扩散模型，研究扩散系数、扩散时间、钢筋位置、氯离子边界质量分数及构件截面尺寸等对氯离子二维扩散的影响程度．结果表明，扩散系数和扩散时间既影响氯离子二维扩散区域，又影响氯离子扩散程度，两者值越大，二维扩散区域越大，氯离子质量分数越高；钢筋位置是决定钢筋初锈时间的重要因素；氯离子边界质量分数对氯离子二维扩散区域均无影响，但对氯离子扩散程度影响明显．
英文摘要：
According to two-dimensional diffusion model, the influence of various factors on two-dimensional diffusion of the chloride ion in conventional cross section is studied, including as diffusion coefficient, diffusion time, reinforcement lo- cation, boundary concentration of chloride ion and cross section dimension. It is shown： diffusion coefficient and diffusion time influence both the diffusion area and the extent of chloride ion; with increasing diffusion coefficient and diffusion time, the diffusion area and the concentration of chloride ion increase; the reinforcement location is the primary factor in determining its rusty time; the boundary concentration of chloride ion has no impact on its diffusion area, but obviously influences its diffusion extent.
