八十年代初期我国地震工程学界中的几位科技人员开始将模糊集合理论应用于地震工程领域。在短短的四年中,已在某些重要方面,取得了令人鼓舞的成就。第一个课题是关于地震烈度和烈度评定。作为地震效应的宏观尺度,地震烈度表在烈度小区划和地震工程的其它战略决策中,都具有十分重要的作用。然而,这种尺度只是地震动后果的主观判断,而不是明确的工程标准。1942年以来,从古登堡(Gutenberg)和李希特(Richter)
In the early 1980s, several scientific and technical personnel in the field of earthquake engineering in our country started to apply fuzzy set theory to the field of seismic engineering. In just four short years, encouraging achievements have been made in some important aspects. The first topic is about earthquake intensity and intensity assessment. As a macroscale of the earthquake effect, the seismic intensity table plays an important role in the sub-regionalization of intensity and other strategic decisions in seismic engineering. However, this measure is only a subjective assessment of the consequences of earthquakes, not a clear engineering standard. Since 1942, Gutenberg and Richter
