| 摘 要： | 本文利用混合模拟方法,合成了加速度反应谱及峰值位移相同,而峰值速度不同的两组人工地震动时程.同时选择典型隧洞,进行了弹塑性地震反应分析,研究了地震波水平输入时,地震动峰值速度对隧洞内力的影响.在软土场地中,当加速度反应谱及峰值位移相同时,峰值速度较大的地震动时程将引起隧洞较大的弯矩和剪力.在硬土场地中,峰值速度对隧洞弯...

| Abstract: | A hybrid simulation method is used to generate two group artificial ground motions that are compatible with the same response spectrum of absolute acceleration and same peak displacement,but different peak velocities.The elastic-plastic seismic response analyses of underground tunnel are performed.The influence of peak ground velocity (PGV) on the internal force of underground tunnel are studied.For the time histories with the same response spectrum and same peak displacement,the larger PGV will cause the l... |
