摘要
针对混凝土氯离子渗透试验中温度、溶液浓度、电极接触电阻等边界条件波动导致的检测误差问题,论文通过正交试验与理论分析,讨论温度、溶液浓度、电极接触电阻等主控因素的影响规律,建立多因素误差量化模型;开发模糊PID恒温控制系统,提出动态补偿策略,使电通量数据离散系数从17.3%降至6.5%。工程案例验证结果表明,修正后氯离子扩散系数评估误差下降至9%,氯离子渗透检测的可靠性得到提高。
Aiming at the problem of detection errors caused by the fluctuations of boundary conditions such as temperature solution concentration and electrode contact resistance in the chloride ion penetration test of concrete,the influence laws of main control factors such as temperature solution concentration and electrode contact resistance are quantified,through orthogonal experiments and theoretical analysis,and a multi-factor error quantification model is established.A fuzzy PID constant control temperature system is developed,and a dynamic compensation strategy is proposed,reducing the coefficient of variation of the electric flux data from 17.3%to 6.5%.Engineering case verification results shows that the evaluation error of the chloride ion diffusion coefficient after correction decreases to 9%,significantly improving the reliability of chloride ion penetration detection.
