本文讨论了用修正麦卡里烈度表表示的大城市区域的地震小区划。使用了关于活断层的位置和它们的相对地震活动水平,断层的三维几何性质,依赖频率的哀减,用场地下面沉积层深度表示的波振幅和局部放大效应的资料和用震中烈度表示的标定方法。证明了这个标定方法与用震级表示的标定是一致的,它可给出统一危险性谱的可靠估计。
This article discusses the subdivision of the earthquake in the metropolitan area, using the modified McCarrior intensity table. Data were used on the locations of active faults and their relative seismic activity levels, the three-dimensional geometric properties of the fault, the frequency-dependent depressions, the amplitudes of wave amplitudes and local magnification effects expressed by the depth of sediment beneath the site, and the calibration in terms of epicenter intensity method. It is proved that this calibration method is consistent with the calibration indicated by magnitude, which gives a reliable estimate of the uniform hazard spectrum.
