| 摘 要： | 根据暴露在感潮河口环境下的2种水灰比RC梁的水工混凝土暴露试验,测定了不同深度处的自由氯离子浓度;推导了混凝土氯离子扩散性能与时间关系的一维模型,并依据一维时变扩散模型计算了水工混凝土的自由氯离子浓度.结果表明,一维模型公式可以较好地模拟该环境条件下水工混凝土氯离子的侵蚀,并可预测长期侵蚀时水工混凝土中的自由氯离子浓度.

| Abstract: | According to the hydraulic concrete of RC beams with two different water cement ratios exposed to the tidal reach,a series of free chloride ion concentrations of different depths are measured. And one-dimension model between diffusion of chloride ion and erosion time is analyzed. Based on one-dimension model,free chloride ion concentrations of the hydraulic concrete beams is calculated. The results show that the erosion of hydraulic concrete exposed to the tidal reach can be simulated and free chloride ion concentrations can be calculated by the one-dimension model. |
