地表地震反应的理论计算

THEORERICAL COMPUTATION OF GROUND SEISIC RESPONSE

摘要:

本文在"水平假定"的前提下,将具多层土的建筑场地看作一单位横截面的层状土柱,并简化为集中质量块的剪切梁计算模型。考虑到土壤的非线性特性,采用稳定的Wilson-θ法计算从基岩到地表的各层土地震反应。最后还指出了本文的工程意义。

Abstract:

On the basis of horizontal assumption, the building site with mnlti-layer soil is regarded as a layered soil column of an unit cross section and is simplified as the sherebeam computing model of the lumped-mass. Taking account of the non-linear characteristics of soils, we have used the method of stable wilson-θ to compute the seismic response of every layer soil from base rock to ground. Finally, it is pointed out that this paper is of some significance in engineering.
