摘要: 为了模拟50年超越概率为10%、2%、1%、震中距40 km的地震,首先产生了基岩地面响应合成时程图,然后以合成的50年超越概率为10%、2%、1%的基岩地震波作为输入,使用一维剪切波理论对穿过场地土层的输入响应进行地震反应计算并分析地表动反应,最终目的是对常德地区某电厂场地进行地震反映分析。计算所得到的加速度时程图、加速度反应谱以及放大谱对工程设计人员有较大的帮助。

Abstract: In this study, the time histories of the synthetic bedrock ground motions have been generated to simulate various earthquake moment magnitudes at probabilities of 10%, 2%, and 1% in fifty years level with an epicentral distances of 40 km. Applying these bedrock time histories into the soil profiles of a power plant site in northern Hunam Province. By using surface seismic shear wave method, which is a one\|dimensional, equivalent\|linear analysis, the ground response under the seismic ground motion was obtained. The computed acceleration time histories, response spectrum and amplification spectrum are most useful parameters for seismic design.
