| 摘 要： | 本文利用山东省及其邻区14个地震的37条等震线拟合山东地区地震烈度衰减公式.I=2.419+1.429M-1.286ln(R+9)σ=0.43认为此公式可以在今后山东省地震烈度区划和工程地震危险性分析中应用.同时还简单地讨论了不同震级、不同岩性地区地震烈度衰减的差异问题.

| Abstract: | The formula of seismic intensity attenuation fitted by using 37 isoseismal lines of 14 earthquakes in Shandong and near area. It is believed that above formula could be applied in seismic intensity zoning and risk analysis of engineering seismics. Differences of seismic intensity attenuation to result from various magnitudes and various lithologic Characters are also discussed. |
