摘要
运用一维土层地震反应的等效线性化波动方法,研究了单层均质土密度、动剪切模量比和阻尼比、土层厚度和土层剪切波速等参数变化对土层地表加速度峰值和反应谱的影响,所得到的结论对于指导地震安全性评价中的勘察试验工作、提高土层地震反应的计算精度具有一定的参考价值。
Using one-dimensional equivalent linear method of soil earthquake response on the basis of the wave motion model, we studied the effects of the variation of some soil parameters, such as the density of single-layer homogeneous soil and its dynamic shear modulus ratio and damping ratio, thickness and shear velocity, etc., on ground surface acceleration peak and response spectra. It is thought that the obtained results have certain reference for guiding exploitation and experiments in seismic safety evaluation and improving calculation precision of soil seismic response.
