摘　　要：对送电线路拔梢钢管杆在常见载荷 (集中力、集中力偶和分段均布力 )作用下的挠度 ,用解析法进行了分析。应用折算惯矩的思路 ,推出了拔梢钢管杆在常见载荷作用下的折算惯矩公式 ,并给出了挠度的简捷计算公式。文中还用实例比较了两种方法计算的结果。The deformation of transmit-electricity steel tube pole under the frequent load including integrated force,integrated torque and distributed force is analyzed using analytical method.The formula of the equivalent inertia is deduced for steel tube pole under frequent load,and the simplified computing formula for its deformation is also given.In this paper,the results of the two computing methods are compared by an example.
