摘要
在总结适用于中国大陆地区使用的建筑能耗分析用室外气象参数的基础上,建立了浅埋地下工程围护结构及周边岩土的传热数学模型。对不同气象参数条件下地下工程围护结构及其周边岩土传热过程进行了数值模拟。结果表明:地下工程围护结构顶板处受到室外气象参数影响较大,不同气象参数对地板传热几乎没有影响。较其他气象参数,中国城市建筑用标准气象数据库误差较大,这可能是由于其原始数据来源于国际地面气象观测数据库,本文认为其不适用于地下工程围护结构传热过程的分析。
Based on the summarization of the meteorological data in building energy analysis used in China mainland, the mathematical model for the underground envelope and the surrounding soils is built in this paper. Numerical simulation is done to analyze the influence of the different meteorologic parameters on the heat transfer progress of the envelope and the soils. The results show that the ceiling is affected by the meteorologic parameters most, while the mean heat flux in the floor is similar under different meteorologic parameter condition. Compared with the other meteorologic parameters, large error appears when using the CTYW （Chinese Typical Year Weather） as the meteorologic parameters. This may due to that the CTYW original database comes from the International Surface Weather Observations. As a result, it is advised that the CTYW is not suitable to do research on the heat transfer research of the underground engineering.
