摘　　要：利用三维有限元结构分析软件3D3S分析了三管铁塔结构在不同风压情况下,建立不同塔柱斜率的模型并分析基础反力的不同参数,计算了在不同风压作用下包括铁塔基础简化至塔脚平面形心处标准组合压力、剪力、弯矩值及单个塔脚最大压力、最大拉力等的基础反力,并通过结果分析得出铁塔在不同风压及塔柱斜率情况下铁塔反力各参数的变化规律。In this paper,the three tube tower structure is analyzed under different wind pressures by using the three-dimensional finite element structure analysis software 3D3S.By establishing models of different tower column slopes and analyze different parameters of foundation reaction force,the foundation reaction force under different wind pressure is calculated.The influencing factors include the standard combined pressure,shear force,bending moment value at the centroid of the tower foundation,the maximum pressure and maximum tension of a single tower foot,etc.Through the result analysis,the variation law of various parameters of tower reaction force under different wind pressure and tower column slope is obtained.
