摘　　要：为解决转角塔在铁塔组立后插入角钢与铁塔接腿角钢连接处出现塌腰或鼓肚的现象,结合实际工程与施工经验,提出了预偏数据几何修正法,对预偏值的取值和基础根开、角钢根开、主角钢坡度调整的计算进行了分析和修正。通过与基础设计数据的对比表明,几何修正法使铁塔的基础施工数据得到了合理的调整、使铁塔和基础达到了设计的预偏效果,并确保了铁塔整体及局部受力的合理与稳定。In order to solve the bulging phenomenon in joints of inserted angle steel and iron tower legs angle steel af- ter assembly of tower, this paper proposes geometric correction method of deviation data by combining with the actual en- gineering and previous construction experience. The deviation value, foot distance of base, foot distance of angle steel, adjustment of main angle steel slope are calculated and analyzed. Comparison of design data, geometric correction method adjusts the foundation construction data of tower reasonably, which makes the design of tower and foundation attaining the deviation effect. Therefore, it ensures the force stability and rationality of the tower.
