| 摘 要： | 场地微动的理论研究和工程应用均基于各向同性介质模型,这与实际情况不符.首次提出了各向异性介质中场地微动的概念,从弹性波理论出发,对各向异性场地微动进行了模拟研究,得出了一些有益结论.这对深入研究各向异性场地条件下场地动力特性、地震动特性预测、结构抗震研究具有非常重要的意义.

| Abstract: | At present, the study of theory and engineering application about ground micro-tremor is based on the hypothesis of isotropy. In fact, the characteristic of soil is usually anisotropy. In this paper, the conception of ground micro-tremor in anisotropy has been put forward. Based on the theory of elastic waves in anisotropy medium and the influence of anisotropy on ground micro-tremor, characteristics of ground micro-tremor are analyzed. They are very important for determining the dynamic properties of soil, predicting the characteristics of ground micro-tremor and studying of the shock resistance of architecture. |
