摘　　要：指出耐张塔采用斜插入式角钢基础,基础留有预偏后铁塔倾斜,主材坡比与原设计坡比相比发生一定的倾斜变化,而基础插入角钢坡比与铁塔坡比必须相一致,因此必须对基础插入角钢做相应的坡比调整。针对耐张塔插入式斜柱基础预偏后对插入主角钢的调整以及如何控制进行分析探讨。Strain towers take oblique plug-in angle iron as the basis that leaves space for the tower tilt after the pre-bias. Compared with the original design, the main material slope ratio has some inclination changes, but the slope ratio of plug-in angel iron and that of the towers must be consistent, therefore, some adjustment must be done on the slope ratio of plug-in angel iron of the basis. This paper analyzes the plug-in angle iron adjustment after the inclination of plug-in based strain towers and the ways to control it.
