为了揭示高海拔地区水泥稳定碎石层养生期温度分布规律,采用有限元软件ABAQUS建立了基于水化热的水泥稳定碎石层养生期三维非稳态计算模型,分析了日最低气温、日温差、太阳辐射总量、风速、水泥稳定碎石厚度及水泥剂量等因素对水泥稳定碎石层养生期温度场分布的影响及其敏感性。分析表明:随着日最低气温、日温差、日太阳辐射总量及水泥剂量的增大,水泥稳定碎石层表面及层中温度逐渐提高;随着风速的增大,水泥稳定碎石层表面及层中温度逐渐降低;水泥稳定碎石层表面最低温度的关键影响因素为风速,层中最低温度的关键影响因素为水泥稳定碎石厚度。 相似文献

The thermal energy storage phase change material used for building has been prepared with a few of fatty acids based on the
principle of binary low eutectic point. The thermal behaviors such as phase transition temperature and enthalpy of compound
energy storage material are researched through differential scanning calorimeter (DSC) and scanning electron microscope (SEM).
The results show that the thermal energy storage phase change composite material can be used in the wall panels well as its
higher latent heat. 相似文献
