摘　　要：针对蒙西地区输变电工程季节性冻胀危害问题,分析研究了冻土的形成原因和影响因素,并从区域地形地貌、水文气象、地层岩性、地下水位等诸多方面出发,结合现场调查取样结果和区域内输变电工程原始资料,作出区域冻胀等级趋势分布图。同时选择结合文献研究及蒙西地区季节性冻土特性,提出了冻胀防治的几种处理措施,对以蒙西地区为代表的季节性冻土区域电力建设研究、电力设施选址及选线阶段具有重要的意义。The seasonal frost heaving hazards of the electrical power transmission and transformation projects in western Inner Mongolia are evaluated.This paper analyzes factors that might potentially cause and influence the seasonal soil frost heave are presented.Based on the regional topography,hydrometeorology,stratum lithology,groundwater level and other aspects,along with the field survey sampling results and the regional engineering original data,the regional frost heaving grade trend distribution map was developed.At the same time,according to the literature research and the characteristics of frozen soil in the western Inner Mongolia,several measures to prevent frost are proposed.This paper provides some significance to the study of the electrical power construction,site selection and alignment selection of electrical power facilities in the region of seasonal frost heaving soils in western part of Inner Mongolia.
