摘要
新的国家地震区划图即中国地震动参数区划图已于 2 0 0 1年 8月正式出版 .该地震区划图包括峰值加速度区划图和反应谱特征周期区划图 .该区划图风险水平为 5 0年超越概率0 .1,比例尺为 1∶4 0 0万 .该区划图已经作为国家标准颁布 .本文介绍了该区划图编制的背景、编图的技术思路以及主要科学问题。
A new set of seismic zoning maps were published in August 1, 2001. It includes two maps, one is the seismic zoning map of peak acceleration, the other is the zoning map of the characteristic period of the response spectrum. The exceeding probability of the map is 10% within 50 years. The scale of the map is 1:4 000 000. These maps serve as the national standard. The background of this project, technical approach and key scientific measures, the basic feature and the application of the maps are introduced in this paper.
