【摘要】 本文根据保定市区工程地质及地震地质条件，采用全概率分析方法，用一维等效线性模型，对不同分区的典型土层进行地震反应分析，并在此基础上确定了市区的设计地震动参数．在某些方面补充了规范的不足，使市区的抗震设防水准更加合理．更多还原

【Abstract】 Considering the conditions of Baoding City’s engineering geology and seismic geology, the typical soil layers in different units are analyzed by the known probabilistic method and one-dimensional equivalent linearization model, and the design ground motion parameters of Baoding City are given in this paper. The determination of these parameters complements the code of Building Earthquake Resistant Design and makes the protection level of Baoding City more reasonable.更多还原
