摘要:: 依据昆明烈度速报台网子台场地钻孔资料、等效剪切波速以及地脉动测试结果,对不同强震动台站的场地划分标准作了对比。结合昆明盆地的地质构造特征,对昆明强震动烈度台站的场地类别作了判定。同时指出,对个别判定指标临近划分标准分界线的台站的分类工作还需进一步研究。

Abstract:: According to the borehole data,equivalent shear-wave velocity,and the measured micro-tremor at the site of the sub-stations of Kunming rapid intensity report network,we compare the standards of classification for soil at the sites of the difffrent strong motion stations.Further,we classify the site of the stations of Kunming rapid intensity report network on the basis of the geolgical structure characterics of the Kunming basin.The determination indexes of a few sub-stations are close to the dividing line given by the standards,and further classification of these stations is necessary.
