本文对地震烈度这个概念作了重新审查,指出地震烈度是地面震动在一定面积范围内的平均程度,只能用在此范围内平均的物理数量来度量.在现阶段,工程设计数据应当选取这个平均数量加上一定的具有合理概率基础的偏差.宏观的和物理的烈度尺度都是需要的,但须以后者为准,以前者为后者的定性描述.对于物理尺度的选择、现行烈度表的修改以及烈度在工程实践中的应用等问题都作了较详细的讨论. This paper reviews the concept of seismic intensity and points out that the seismic intensity is the average degree of ground vibration within a certain area and can only be measured by the average physical quantity in this range. At this stage, the engineering design data should select this The average amount plus some bias with a reasonable probability basis.Macro and physical intensity scales are needed, whichever is the latter, with the latter being a qualitative description of the latter.For physical scale selection, the current intensity table The revision and the application of intensity in engineering practice have been discussed in more detail.
