在高纬度多年冻土区采用灌注桩基础时，由于对多年冻土中温度的分布情况、桩基施工后对地温的影响认识不够，致使设计偏于保守。本文结合在高纬度多年冻土地区建设的220kV塔河—漠河送电线路新建工程采用灌注桩基础的实际情况，在对多年冻土进行物理力学试验的基础上，通过对桩身混凝土温度监测、场地地温观测和桩基周边冻土地温变化过程的监测，对高纬度多年冻土区的桩基础设计、施工有了进一步认识，使桩基础设计具有针对性、科学性与经济性。

Using bored pile foundation in permafrost region of high latitude, because of the distribution of temperature In permafrost regions, not enough understanding of ground temperature inlfuence after the pile foundation construction,leading to the design is to conservative. Combined the construction of the bored pile foundation of Mohe 220kV substation in high latitude permafrost area, based on the physical mechanical test of the permafrost, according to the temperature monitoring of the the pile body concrete and the observation of ground temperature and the change of the temperature pile of foundation surrounding,We have a further understanding of the design of pile foundation in permafrost region in the high latitude, making the design of pile foundation with pertinence, scientiifcity and economy .
