摘　　要：依据某工程的实际情况,建立了输电塔有限元模型,通过ANSYS中的CFD模块计算了输电塔在0°,45°和90°风向角下的体型系数,并与规范中的体型系数作了对比,结果表明:规范给出的体型系数值比数值模拟偏小,规范中钢管塔体型系数的计算方法有待改进。According to the actual situation of an engineering, this paper established the transmission tower finite element model, through the CFD module in ANSYS calculated the shape coefficient of transmission tower in 0 degrees, 45 degree and 90 degree wind angle, and compared with the shape coefficient in standard, the results showed that ： the shape coefficient of standard gave smaller than numerical simulation, the cal-culation method of steel tower shape coefficient in standard should be improved.
