| 摘 要： | 新发现的冀东南堡油田位于地震和断裂活动较强的渤海湾地区,抗震设防问题不容忽视。本文分析了油田所在地区的地震活动和地震构造环境,并在此基础上划分出了潜在震源区,确定了地震动衰减关系,进行了地震危险性分析。然后根据油田周边相关工程的工程地质条件特征,建立了场地土动力模型,进行了土层地震反应计算,确定了场地设计地震动参数。结果表明,局部场地条件对地震动峰值和反应谱的影响较大,需对场地工程地质条件进行详细研究。

| Abstract: | Nanpu Oilfield that is situated in the Bohai Gulf, where the seismicity and fault activity are strong enough so that the potential earthquake risk is a big concern. On the basis of analysis on seismicity and seismotectonic background of the oilfield, the potential source zones are delineated, and the ground motion attenuation relation is determined. Then the soil dynamic model is made according to the engineering geologic character. Finally, the site design parameters are determined through calculation of site soil seismic response. Our results show that the local site condition has an important effect on peak acceleration and response spectrum, and further investigation on engineering geologic condition should be carried out in the future. |
