%X 本文收集了云南地区共计620组的三分量加速度记录中的加速度峰值和加速度峰值比&#65292;按照场地条件、震中距、震级等因素统计分析了V/H加速度谱值比并给出了V/H谱值比的取值建议。结果表明&#65306;土层和基岩场地条件下V/H的均值并不相同&#65292;场地的软硬对V/H的数值变化影响较大&#65307;V/H地面峰值加速度的近场与远场处仅在I类场地下大于0.65&#65292;其余场地类型下均小于0.65&#65307;V/H的水平向和竖向反应谱谱值比是一个周期函数&#65292;竖谱值特征周期基本等于水平向反应谱特征周期&#65292;但在较长周期下速度慢于水平方向。<br>This paper collected the peak acceleration and peak acceleration ratio from a total of 620 sets of three-component acceleration records in the Yunnan region. It statistically analyzed the V/H accele- ration spectrum value ratio based on factors such as site conditions, epicentral distance, and magnitude, and provided suggestions for the value range of the V/H spectrum ratio. The results indicate that the mean V/H values under soil and rock site conditions are not the same, and the stiffness of the site has a significant impact on the numerical variation of V/H; the near-field and far-field ground peak acceleration of V/H is only greater than 0.65 under Class I sites, and is less than 0.65 under all other site types; the horizontal and vertical response spectrum value ratios of V/H are periodic functions, with the vertical spectrum characteristic period essentially equal to the horizontal response spectrum characteristic period, but the velocity is slower than the horizontal direction at longer periods.
