摘　　要：以中国石化仪征化纤股份有限公司厂区(以下简称仪征化纤厂区)为例,研究大型厂矿企业地震小区划特征,论证了工作区地震环境、钻孔布设、工程地质分区、加速度时程合成、地震动效应分析、地震小区划分区等。根据仪征化纤厂区的场地地质条件和大量的地震效应计算结果,将厂区分为三个小区,给出各小区的设计地震动参数,同时编制了地震动小区划图和地震地质灾害小区划图。将地震动小区划结果与相关规范作了一些比较,指出相关规范中一些不足之处。提出应对大型厂矿企业,甚至城镇、新区或城市市区开展地震小区划工作,这有利于规划建设,提高社会防震减灾能力。Taking Sinopec Yizheng Chemical co., LTD. factory (hereinafter referred to as Yizheng Chemical Fiber Factory) as an example, the characteristics of seismic microzonation for Large Factories and Mines are studied. The research demonstrated the seismic environment, borehole layout, engineering geological zoning, acceleration time history synthesis, analysis of seismic effect, seismic microzonation, etc. According to the results of the site geological conditions and a lot of seismic effects of Yizheng Chemical Fiber Factory, the factory is divided into three districts;the parameters of aseismic design for each district are also given, at the same time, and the seismic microzonation map and seismic geological disaster zoning map are formulated. By comparing the seismic microzonation results with some related seismic codes, this article points out some shortcomings in the related seismic codes. The seismic microzonation of large factories and mines, and even town, district or city urban, which is conducive to the planning and construction, improves the ability of society of earthquake prevention and disaster reduction.
