摘要
通过实际土层地震反应结果的统计分析和强震加速度观测结果的对比 ,讨论了不同场地条件对基岩峰值加速度的放大效应及其特点。该分析可为地震动参数区划图编制和地震安全性评价中场地效应的估计。
By statistical analysis of earthquake response result of real layered soil and comparison with observation result of acceleration of strong earthquakes, this paper discusses the amplification effect of bedrock peak acceleration caused by different site conditions and its characteristics. The analysis result can provide a reference for compiling zoning map of an area from ground motion parameters, evaluation of site effect in seismic safety analysis, and estimation of site ground motion according to its bedrock motion.
