提出了一种考虑等效线弹性系数和等效阻尼比的水平土层地震反应随深度变化的分析方法。说明了该程序的使用，并将其结果与记录值和使用恒定阻尼解的计算值进行了比较。这些比较表明，与恒定阻尼解相比，可变阻尼解提供的响应值往往与记录值更符合。当矿床由基本上具有相似特性的土壤组成时，差异似乎不是很大。当矿床由性质差异很大的子层组成时，差别就大得多。
An analytical procedure for the evaluation of the seismic response of horizontal soil layers incorporating equivalent linear moduli and damping ratios varying with depth is presented. The use of this procedure is illustrated and its results compared to recorded values and to computed values using a constant damping solution. These comparisons indicate that the variable damping solution often provides response values that are in better agreement with recorded values than those obtained from a constant damping solution. The difference does not appear to be very great when the deposit consists of soils that are essentially of similar characteristics. Much greater differences are obtained when the deposit consists of sublayers having greatly varying charactristics.
