The result indicated that, when seismic motion was unidirectional velocity pulse, the parted diploid-mechanism was more reasonable than unitive diploid-mechanism. However the unitive diploid-mechanism is more suitable for the analysis of bidirectional velocity pulse action. 结果表明:单向速度脉冲地震动作用时,双机制分合法比双机制统一法更合理,双机制统一法更宜于分析双向速度脉冲作用。
Inputting the near fault unidirectional and bidirectional velocity big pulse, complex site response is calculated by equivalent linearization method, the result is examined by itself. Rational condition and limitation of the traditional equivalent linearization method in this project are pointed out. 通过近断层单向、双向速度大脉冲输入的自检验分析,指出了工程中传统等效线性化方法的适用条件及局限性。
