【摘要】 在我国大多数地区,由于强震观测记录缺乏,难以得到某一研究区的地震动衰减规律,从而无法为工程抗震设防提供有效的数字依据。选择既有强震资料,又有烈度资料的美国西部地区作为参考区,估计出荆州长江大桥地区地震动衰减规律,为大桥抗震设防提供了依据。更多还原

【Abstract】 In most regions of our country,because of the lack of the strong earthquake’s prognosticates record,it is hard to get the ground motion attenuation laws of a research area,and so the valid figure materials can’t be got for the engineering anti-earthquake basis.This paper takes west America which both has the strong earthquake data and the earthquake intensity data as a referenced area to estimate the ground motion attenuation laws of Jing Zhou Chang Jiang bridge,and also offers some useful anti-earthquake data material for the big bridge.更多还原
