摘要
通过理论分析,提出了一种新的自然环境温度作用谱,并通过实测数据验证了其合理性。通过对遮挡与未遮挡两种条件下不同深度处混凝土内部温度实测数据的研究,得到了这两种条件下混凝土内部响应温度一维传输规律。结果表明:不论遮挡还是未遮挡条件下,混凝土内部温度响应与自然环境温度作用存在很强的相关性。但在这两种条件下混凝土内部温度响应波幅、混凝土内部温度与自然环境温度极值大小之间的关系、响应敏感度之间存在差异。
The action spectrum of temperature in natural environment was deduced through the theoretical analysis,and its rationality was proved by measured data.The rules of response temperature of concrete under the influence of one-dimensional transmission in two different conditions was obtained by the research of measured data for response temperature of concrete in different depths under two conditions with shelter and without shelter.The results show that there is a strong correlation between the temperature response of concrete and the temperature of natural environment,whether it is sheltered or not.But there are differences in the internal temperature response of concrete under these two conditions,it main show:the amplitude of response temperature,the relationship between the size of extremum for the internal temperature of concrete and the natural environment temperature,the response sensitivity.
