摘要
Abstract
Relative to the numerous intensive studies on frost-harm of tunnel in frozen earth, the studies on heat-harm of tunnel in high geo-temperature region were less. Moreover, most of them were particularly only on simulation of geo-temperature field, or on discussion of technical measures for construction, or on general estimation of heat-harm of tunnel; however, studies on thermal insulation technology and efficiency of lowering the temperature were much less. In this article, by numerical simulation, the trial calculation and analysis on the thermal insulation effect and refrigerating power of different material in different geo-temperature conditions were carried out to determine the refrigerating power value and the refrigerant dosage. And then by calculation, the recharge magnitude of refrigerating power corresponding to the different thickness of thermal insulation material was obtained, and the relationship between them was analyzed and worked out either.关键词
