摘要
本文首先根据弹性波动理论给出了推算地震动转动分量的方法。然后对沈阳地区跨越浑河的60kv线路的输电塔进行了研究,建立了在水平与摇摆地震动联合作用下输电塔—电缆体系的振动方程;采用作者编制的TCCV90数值积分计算机程序对塔—缆体系进行了地震反应分析,得到了一些有意义的结果。
In this paper, first of all, the method to estimate the rotational components of ground motions is given according to the theory of elastic wave propation. And then, the system composed, of 60 KVtransmission tines and their supporting towers crossing the Hun river in Shenyang area is analyzed The equation of vibration for the tower—line coupting system is derived under the combined avtion of horizontal and rocking sersmic motions. By use of TCCV90 computer programme compited by the authors of this paper, xome results with practical singiflcance are obtained, referring to the systematic seisnuc resoinse abaktsis.
