摘　　要：输电杆塔基础承载的输电线路是高负荷电能输送的载体,也是重要的生命线结构工程,其安全性直接影响整个电网的稳定性与可靠度.本文首先对杆塔基础开裂特点及原因进行分析,然后结合输电杆塔实际情况,提出分级检测方法.针对不同的级别确定不同的检测项目,并对不同的检测结果进行分级量化.依照状态检修的思想,采用层次分析法,对不同的检测项目进行量化评估,得到总分,根据总分范围给定处理方案,为输电杆塔基础裂缝运行与维护提供依据.The transmission lines supported by transmission tower foundation is the carrier of high load pow- er, and important lifeline engineering structure. Its safety directly affects the stability and reliability of the whole grid. This paper firstly analyzes the cracking characteristics and causes of tower foundation; secondly, combiming with the practical situation, a hierarchical detection method is put forward. According to different levels the different testing items are determined; and according to different test results, different quantitative classifications are made. Different levels for different detection projects, and different detection results are classified and quantified. In accordance with the idea of condition based maintenance, using the analytic hier- archy process （AHP）, quantitative assessment of different test items, the total score is obtained. Based on the score range, the treatment scheme is given; and the basis for transmission tower foundation cracks run- ning and maintenance is provided.
