锥型钢管混凝土基础在冻土地区应用研究与探讨

Research and Discussion on Application of Cone-shaped Concrete Filled Steel Tube Foundation in Frozen Soil Area

根据青海省冻土的特点,首次提出输电线路铁塔基础在冻土地区采用钢管混凝土基础的可行性。从理论上分析了其抗冻的受力机理,体现了其技术先进适用、经济合理、资源节约、环境友好的特点。

According to the characteristics of permafrost in Qinghai Province,the feasibility of using concrete-filled steel tube foundations for transmission line tower foundations in permafrost areas is proposed for the first time.Theoretical analysis of its anti-freezing force mechanism reflects its characteristics of advanced technology,application,economy and reasonableness,resource conservation,and environmental friendliness.
