摘要
本文回顾对比了我国不同时期地震烈度区划的基本方法和结果,分析了这些区划成功与缺陷的根本原因.文中强调指出,当前地震区划采用地震烈度危险性概率分析方法已经使基本烈度概念开始消亡.其区划结果理应给出全部概率信息,以适应我国《建筑结构设计统一标准》的需求.文末对我国未来地震烈度区划的理论框架进行了初步探讨.
In this paper,it is reviewed and compared that the basic methods and the maps of earthquake in-tensity zonation for different duration of China.And the reason of succeeding or not for the zonationsis analyzed.simultaneously,it is pointed out that the idea of the basic intensity is beginning to disap-pear because of using the method of earthquake hazard analysis in the earthquake zonation and now allof the probability information should be given out in the zonation maps for fitting the requirement ofUniform Standard of Building Structure Designs.In the end of this paper,it is preliminary discussedthe theory frame of the eathquake intensity zonation of China in the future.
