Abstract
This study is being conducted to clarify the heat load characteristics of underground structures. The authors have sought to achieve this by clarifying the heat and moisture behavior of an underground basement and surrounding ground, and acquiring basic data for computational analysis. This paper presents measurement results acquired over approximately one year of field experiments on an underground experimental basement under internal heat generation conditions, commenced in October 2004. The authors also present the results of analyses on the heat and moisture behavior of the experimental basement and ground, the influence of internal heat generation on the surrounding ground, the condensation behavior, the interrelationship between precipitation and the fluctuation of moisture content in the ground, the annual mean heating load per unit area, and other factors.
