摘要
针对送电线路杆塔在高寒地区发生因地基土冻胀基础失稳造成的倒杆及倒塔的问题，研究探讨了冻土地基对杆塔基础稳定的影响原因、影响程度及防冻胀措施，为在架空输电线路杆塔地基与基础设计中消除或减少地基土冻胀危害，提供了具有实用价值的地基冻胀力的分析、计算方法和防冻胀的措施。
Aimed at destabilization of foundation leading to pole failure of transmission line by frozen-heave of soil,it is discussed that frozen foundation affects on stabilization of pole foundation. The analysis and calculation methodof frozen-heave force and preventive measures are submitted.
