摘要
本文讨论了地震危险区划中的数值模型,并把目前比较成功的几个岩石破坏的数值准则应用于地震危险性的估计,通过怀来—张家口地区和鄂尔多斯周缘断层带应力场的计算和地震危险性的评价,说明数值方法可以作为地震危险区划工作和探索地震预报的一个新手段。
In this paper, we discussed a numerical model in identification of earthquake risk and applied some numerical criteria which is proved to be effective through rock experiments and finite element computation to estimate failure earthquake risk. According to the practice of calculating the stress field of fault zone and estimating earthquake risk in the Huailai-Zhangjiakou area and the fault zone around the Erduos block,the numerical modeling may be used as a method for identifying earthquake-prone areas and be also considered as a methodology in earthquake prediction.
