| 摘 要： | 本文通过对基本烈度为7°的西宁市地震小区划实际资料的分析及与钻孔剖面等对比,发现地面脉动功率谱与地面运动水平峰值加速度、地面运动反应谱均有较好的对应性。从一定意义上讲,地面脉动能更直接地反映出一定场地条件下第四系复盖层的工程地质性质,所以可作为一种既简便又经济的工程场地评价方法,与其他方法配合使用。

| Abstract: | In this paper, it is found that power spectrum of earth tremor corresponds to acceleration peak value and response spectrum of ground motion using comparison analyses between the practical data on the seismic microzoning of Xining City, where the basic intensity is 7 degrees, and profiles of borehole is well. Therefore, in this context, the earth tremor can indicate the engineering-geology properties of Quaternary overburden layer under a certain site condition more directly, and the method of evaluating site by earth tremor may be regarded as a simple, convenient, and economic one of evaluating engineering site, used with other methods together. |
