软弱夹层对SV波场地放大效应的影响
Influence of Soft Interlayer on Site Amplification Effect of Plane SV Wave
【摘要】 通过建立单向弹性土层和半空间的精确动力刚度矩阵,利用场地离散动力平衡方程求解SV波入射时场地位移放大系数,即SV波入射时土层顶面位移与控制点位移的比值。通过实际算例分析层状场地中的软弱夹层对SV波场地放大效应的影响。
【Abstract】 The precise dynamic-stiffness-matrix is built for one-way elastic soil layer and semi-space.The amplification coefficient of SV wave is calculated by site discrete power balance equation,i.e.the ratio of the top surface displacement and control point displacement of the soil layer during the incidence of SV wave.The detailed examples are adopted to analyze the influence of the soft interlayer of the bedded ground on the site amplification effect of SV waves.
