摘要:
研究自然环境中空气湿度变化和混凝土内湿度响应规律,构筑自然环境中空气湿度作用谱和混凝土内湿度响应谱模型.基于饱和水汽压方程,探讨环境湿度采用相对湿度和水汽密度表达形式间的关联,利用现场实测结果验证了所建模型的合理性,并研究了基于历年气象资料构筑典型季节和全年环境湿度作用谱的可行性.试验结果表明,所构筑的自然环境中空气湿度作用谱和混凝土内湿度响应谱模型可描述自然环境湿度变化与混凝土内湿度响应规律,其理论拟合曲线与实测结果吻合较好,研究可为人工模拟环境试验设定湿度参数和定量对比提供支持.
Abstract:
The action spectrum of air humidity in natural environment and the response spectrum of humidity of the concrete were presented according to the laws of humidity change in the natural environment, and the concrete were studied. Based on the saturation vapor pressure equation, the relationship between relative humidity and water vapor density was investigated, and the rationality of the models was verified through testing. Moreover, the feasibility of deducing the humidity spectrum was studied from meteorological data from past years. The results show that the models of the natural environment humidity action spectrum and the concrete humidity response spectrum can be used to describe the laws of humidity change, and the resulting curves are fit to describe the test results. The action spectrum of the natural environment humidity can be obtained from meteorological data, which provides the theoretic basis and the criterion for the humidity parameters of the artificial simulation environment test.
