我国西部多年冻土地温带与工程建筑物稳定性

Permafrost Zonation of Crround Temperature and Stability of Engineering Constructions in the Western Region, China

气候转暖对多年冻土的地温带及工程性质产生较大的影响,本文通过气温和地温与冻土稳定性关系的分析,考虑工程建筑物的稳定性和持久性,以及冻土工程性质的变化,将冰冻圈多年冻土分为三大地温带,给出了气候转暖后地温带及工程性质的变化。在此基础上,讨论气候转暖后建筑物稳定性的变化及相应的对策。

Climate warming has great influence on the permafrost zonation of ground temperature and engineering property. Permafrost in cryosphere is divided into three zonations of ground temperature by analysis of the relations between air and ground temperatures, the permafrost stability, considering stability and durability of buildings, and considering change of engineering property of permafrost. Changes of ground temperature zonations and engineering property are given under climate warming. Finally, the stability and durability of buildings are discussed, and the related strategies are given under climate warming.
