摘要
针对目前甘肃地震应急指挥技术系统中使用的地震影响场模型参数存在的不足,本文结合甘肃地区活动构造特点,建立了适用于本地区的分区地震烈度影响场模型参数。并通过实例检验证明,使用新参数得到的不同烈度区的烈度分布与实际烈度分布的接近程度有明显提高,可为震后合理判断烈度分布、提高震害快速评估结果的合理性与准确性提供有益的帮助。此外,本文基于ArcGIS Engine、采用VB6.0实现了地震影响场矢量文件的自动生成,可为今后发生破坏性地震时,通过与省地震应急基础数据库中其他空间数据的叠加分析,在应急救援初期制作各类灾区专题图件及辅助决策提供服务。
Aiming at the problem of the earthquake affecting field model parameters of the earthquake emergency commanding technical system of Gansu province, the new model parameters was achieved in this paper. By comparing the intensity distribution computed by new parameters with the actual one, we find that our new parameters are helpfitl for improve the accuracy of intensity distribution and the fast earthquake disaster evaluation. In addition, for the purposes of thematic map production and emergency rescue of post earthquake stricken-region, the automatic generation for the vector files of intensity affecting field was achieved also based on Arcgis engine＆vb6.0.
