摘　　要：南海明珠电视塔高３８８ｍ，体型为不对称螺旋形。本文针对其结构的不对称性，分别采用只考虑单向振型和同时考虑两向及扭转振型的两种动力分析方法计算结构的动力特性和水平地震下的地震作用效应，并对两者进行对比，分析其差别。The 388 meters high Nanhaimingzhu TV -- Tower has a nonsymmetric spiral shape. In this paper, in the light of its nonsymmetric structure, two different dynamic analysis methods are used to study its dynamic characteristics and horizontal earthquake effects. The one considers one--direction mode only, the other considers two--direcdirections and torsion mudes simultaneously. Then the differences between this two are compared.
