澳门地区建筑物设计地震动参数研究

Study on Design Ground Motion Parameters for Building Structures in Macao

根据澳门地区地震环境、场地特点,利用本地区的工程地质钻孔资料和相似地区的场地设计地震动参数研究成果,结合少量工程地震钻孔剖面的土层反应分析结果,合理地确定了澳门地区不同建筑场地类别的设计地震动参数,对于Ⅱ、Ⅲ类场地,按存在或不存在成片淤泥两种情况进行了反应谱特征周期参数分组,为澳门地区一般建筑工程的抗震设计提供了参考依据。

Utilizing a large number of engineering geological borehole data in the local area and results of design ground motion parameters of sites in similar regions, plus soil response analysis results of soil profiles from several engineering seismological boreholes in Macao, appropriate design ground motion parameters of different kinds of engineering sites in Macao have been determined. For sites of classes II and III, characteristic period parameters of response spectra have been categorized into sites with or without continuous mud. The results of this study provide a scientific reference for seismic design of general buildings in Macao.
