摘要:
地震对高压输电线铁塔的安全性能有重要影响。通过建立高压输电线铁塔模型，采用有限元方法对受7级和8级地震影响的高压输电线铁塔的力学行为进行数值模拟与分析。计算结果表明：在地震作用下高压输电线铁塔t=3-4s时加速度最大，其应力也相应较大；在7级地震时最大应力值远小于材料的许可应力，高压输电线铁塔在7级地震过程中是安全的，但是8级地震时，最大应力值已经达到234MPa，超过Q345许可应力230MPa，高压线铁塔就处于不安全运行状态。
Abstract:
The safety performance of highvoltage transmission tower can be affected obviously by earthquake. With finite element method, the model of highvoltage transmission tower was established to study its strength and safety, which was affected by 7 magnitude earthquake and 8 magnitude earthquake. The numerical simulation results showed that the acceleration of highvoltage transmission tower is biggest at 3s4s with earthquake, and at the same time the stress of tower is larger, with 8 magnitude earthquake the maximum stress value is much smaller than the material allowable stress, highvoltage transmission tower is safe. But with 7 magnitude earthquake the maximum stress value 234MPa is bigger than the allowable stress 230MPa of Q345, which may cause the highvoltage transmission tower in the state of unsafe operation.
