| 摘 要： | 文章利用沈阳地区详尽的深、浅部勘探资料和钻孔等资料,对于密度均匀地区运用多功能商业软件处理海量数据,而对于数据稀少和分布不均匀的地区,则运用自主开发的Spline函数建模方法连结空间随机分布的深度数据,建立了沈阳(抚顺)地区符合地质学和地形学理论三维不均匀地层结构模型,为进一步开展基于活断层的强地震动预测(模拟)奠定了基础。

| Abstract: | In this paper,based on the elaborate information about deep and shallow geophysical data and drill data etc.in Shenyang area the three-dimensional theoretical nonuniform stratum structure model is built up,which accords with the geology and geomorphology in Shenyang(Fushun included) area.The multifunctional commercial software is used to process a great number of the uniform density areas,and the independently developed Spline function modeling method is used to connect the spatial stochastic distribution data for the areas with rare data or nonuniformly distributed data.This model lay a foundation of predicting strong earthquake motion based on active fault. |
