本文通过对地震地质背景分析和数学有限元计算,最后提出对焦作-鹤壁矿区地震危险性工程地质评价。其结论认为:百年内,未来区域危险地震不大于6级,其中焦作矿区东部可能受到七度场影响;鹤壁矿区主要受来自外围场影响,但亦不会大于七度。因此二矿区均属基本安全区,除重要地面建筑物按七度设防外,一般可不设防。
Based on the analysis of seismic geological background and mathematical finite element calculation, this paper puts forward the engineering geological evaluation of seismic hazard in Jiaozuo-Hebi Mining Area. The conclusion is that within one hundred years, the future dangerous earthquakes in the area will not exceed 6 levels, of which the eastern part of Jiaozuo may be affected by the seventh-degree field. The Hebi mining area is mainly affected by the external field but will not be greater than seven degrees. Therefore, the two mining areas belong to the basic security zone, except for important ground buildings at seven degrees fortification, generally not fortified.
