摘　　要：西北荒漠地区拥有大量高压电塔,然而煤层采动对这些塔基的安全性构成了严重威胁。为了确保采动对高压输电线路的安全性,本研究采用了概率积分法来预测高压线塔基地表移动变形,并对受采动影响的塔基进行了分析和评估,同时提出了改造加固技术的具体方案。研究结果显示,通过采用杆塔基础加固改造、杆塔的纠倾和杆塔平移等措施,可以有效解决高压电线塔在井田采动作用下出现的倾斜、坍塌和变形等问题。这种改造措施不仅保证了电力供应的安全性和稳定性,还降低了对生态环境的损害,并避免了由输电线路坍塌引发的人身伤害,对于解决西北荒漠地区高压电塔受采动影响的安全问题具有重要意义。这项研究的成果不仅保障了电力供应的可靠性,还为其他类似工程提供了有价值的实施指导。Urban roads,rainwater discharge,models,and influencing factors.The northwest desert region has a large number of high-voltage power towers,but coal mining poses a serious threat to the safety of these tower foundations.In order to ensure the safety of high-voltage transmission lines caused by mining,this study used probability integration method to predict the movement and deformation of the high-voltage tower base,and analyzed and evaluated the tower base affected by mining.At the same time,specific plans for renovation and reinforcement technology were proposed.The research results show that measures such as strengthening and renovating the tower foundation,rectifying the inclination of the tower,and translating the tower can effectively solve the problems of inclination,collapse,and deformation of high-voltage power transmission towers under the action of mining in the mine field.This transformation measure not only ensures the safety and stability of power supply,but also reduces the damage to the ecological environment and avoids personal injury caused by the collapse of transmission lines.It is of great significance for solving the safety problem of high-voltage power towers affected by mining in the northwest desert region.The results of this study not only ensure the reliability of power supply,but also provide valuable implementation guidance for other similar projects.
