| 摘 要： | 根据季节性冻土地区地质情况，结合我国规范的要求，在季节性冻土地区需要根据冻土地区基础设计原则进行输电线路杆塔基础设计，验算输电杆塔基础极限抗冻拔稳定。另外某些输电杆塔基础需要采取技术措施，包括采用回填非冻胀性材料、坡形基础或桩基础等使冻土地区输电线路杆塔基础设计更符合地理、地质情况。

| Abstract: | The transmission tower foundation in seasonal frozen soil areas should be designed based on the geological condition and considering the request of our country.The ultimate freezing resistance of foundations should be examined;and technical measures such as backfilling of non-heaving materials,using slope-shape foundations or pile foundations,should be taken,so as to satisfy the geological and geographic requirements. |
