| 摘 要： | 为分析典型特高压钢管塔的抗震能力,利用有限元软件ANSYS建立了7种不同呼高的典型特高压交流直线塔的有限元模型,并采用三角级数迭加法模拟了典型地震烈度和场地组合下的地震动加速度时程,对典型直线型单基杆塔进行了地震动反应谱分析,结果表明:1000kV典型特高压钢管塔在典型地震烈度和场地组合条件下具有足够的抗震能力。

| Abstract: | In order to analyze the seismic capacity of typical UHV steel tube tower,this paper uses the finite element software ANSYS to establish seven different call high typical UHV linear finite element model of the tower,and uses trigonometric series overlapping addition to simulate the typical earthquake intensity and acceleration time history under the combination of ground motions,the typical linear single-base tower on the seismic response spectrum analysis,the results show that the typical 1000kV UHV pole tower in a typical earthquake intensity and site conditions have enough aseismic ability. |
