ANALYSIS ON AMPLIFICATION EFFECT OF BEDROCK PEAK ACCELERATION CAUSED BY SITE SOIL

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.
