| 摘 要： | 本文根据保定市及周围地区的地震地质环境，在地震危险性分析的基础上，采用等效线性一维波动方程进行土层的地震反应分析。给出50年超越概率63％、10％、2％基岩和地面的水平向峰值加速度、反应谱（场址基本烈度Ⅶ度）和地震影响系数最大值。该结果为抗震设计提供了可靠依据，具有应用价值。

| Abstract: | Considering the seismic environment of Baoding city and its neighboring area,the seismic hazard for baoding city area is analyzed by the known probabilistic method,and considering the effect the earthquake responses of soil layers are also analyzed by one-dimensional wave motion and design ground motion parameters of site for exceedance probability 63,10 and 2 per cent in fifty years are given in this paper. The parameters include horizontal acceleration response spectra and peak accelerations of rock and free field ground surface. The results can be used in design of earthquake engineering in the site district. |
