摘要:
本文从概率地震区划图是否可以检验的讨论切入,阐述了检验概率区划图的思路。收集、整理区划图颁布以后发生的5级以上(含)地震的等震线数据,在GIS平台上建立了投影方式、投影参数、比例尺一致的地震区划图和等震线信息系统。对等震线不完全、没有等震线数据的地震,借助GIS空间操作的功能、据地震动衰减关系推算,生成、完善相应的等震线。将各个地震的等震线图逐一叠加在区划图上,留大舍小,生成最大烈度差图层。统计出各正烈度差的分布范围,低估、严重低估的总面积及相应的百分比。据此,建议了区划方法改进的研究重点。
Abstract:
Starting from the argument if seismic zoning map compiled by probabilistic procedure could be tested, a way to test probabilistic zoning map is presented in this paper. The isoseismals of earthquakes with magnitude no less than 5 occurred after the map issued are collected, and then an information system of seismic zoning map and isoseismals is built on GIS platform with the same projection manner and same parameters. For those quakes without or with just incomplete isoseismal data, the isoseismials are generated or completed by regional attenuation relationship and the spatial manipulation functions of GIS. The isoseismals are overlaid on the zoning map one by one, and the largest Intensity difference is kept for each area, finally a maximum Intensity difference map is worked out. The areas with positive Intensity difference are marked. The total areas with underestimation and badly underestimation on the zoning map are counted up and percentages of them to the corresponding total areas on China main land are analyzed. The main point for improvement of the zoning is suggested from the test.
