多年冻土地区给排水工程构筑物的模拟理论分析

Structural simulation theory analysis of water supply and drainage engineering in permafrost soil zone

结合高原多年冻土地区的特性,分析了给排水构筑物的保温技术,建立了热量传导和冻土冻融耦合分析模型,进行了冻土地区构筑物的热工计算,探讨了冻土冻胀力对构筑物的破坏机理,为给排水构筑物的设计提供了依据。

Combining with plateau permafrost soil features,the paper analyzes thermal insulation technology of water supply and drainage structure,establishes coupling analysis model of thermal conduction and frost-thaw,carries out thermal computation of structure in permafrost soil zone,and finally explores the damage mechanism of frost-heave force upon structures,which has provided some basis for water supply and drainage structure.
