摘　　要：针对输电线路杆塔基础被埋置于孤堡中造成重大安全隐患的问题,笔者提出了进行孤堡输电线路杆塔基础偏移实时监测方法。首先确立输电线路杆塔基础位移检测笛卡尔坐标系,有效获取孤堡杆塔基础支撑脚处位移量;其次提出以笛卡尔坐标系为基准的孤堡输电线路杆塔基础偏移算法;最后结合相关检测数据进行算法验证,获取了一段时间内基础位移与时间变化关系曲线。对该曲线的分析表明,文中提出的方法对孤堡输电杆塔基础偏移预警效果好精度高。Aiming at the serious safety problem of which the tower foundation of transmission line is isolated, the paper puts forward a real-time monitoring method for the tower foundation. Firstly, a Cartesian coordinate system for skewing of the tower transmission is established and the skewing distance at the supporting point of the tower foundation is obtained effectively. Secondly, an algorithm to calculate the skewing distance of the tower foundation based on the coordinate system is put forward. With the algorithm, the relationship between skewing and time can be got. Finally, this paper presents experiment data and curve. The analysis indicates that the method presented in this paper has good performance for on-line monitoring of the tower skewing and has good accuracy.
