【摘要】 工程场地地震危险性分析研究是指根据工程建设场地的场地条件和对历史上发生的地震参数统计,对研究地区的工程建设场地在未来可能遭受到的地震影响程度做出的科学评价。是在对工程建设场地所在的地震与地质环境条件进行详细研究分析的基础上,以地震的震源、场地条件为基础,从工程的角度来研究地震发生后的传播、衰减规律和场地地震液化效应。其目的是为工程结构抗震设计提供依据。本研究是在导师李向新负责的云南省自然科学基金项目《基于GIS的昆明市道路网抗震性评价及灾害预测》的研究的基础上进行的,主要是将GIS应用于工程场地地震危险性分析中,利用GIS强大的空间数据存储和管理、空间分析以及可视化功能,将工程场地钻孔数据进行系统化的管理和分析,并可视化显示分析结果。本文主要利用ArcGIS系列软件提供的二次开发组件Arc Engine开发出工程场地地震危险性分析系统。本文在详细研究了前人进行工程场地地震危险性分析方法的基础上开发出工程场地地震液化空间分布、场地反应谱特征周期空间分布、地震影响场生成等模块。其中研究内容主要包括以下几个方面：1.工程场地地震危险性分析的基本理论方法；2.地震动参数衰减模型和工程场地地震液化模型；3.GIS应用于工程场地地震危险性分析的方法；4.工程场地地震危险性分析数据库的设计和建立；5.将计算模型嵌入GIS系统中,开发出有着友好人机交互界面的系统,更具直观操作性；总体来说,基于GIS工程场地的地震危险性分析系统可以为工程场地数据存储管理提供合理的方法,为结果的直观展示提供方便快捷的手段,为城区建设提供场地资料,为城市工程结构抗震设计提供帮助。更多还原

【Abstract】 Seismic hazard analysis for engineering site research means to scientifically evaluate on the earthquake influence degree for study area when suffered in the fixture according to the statistics of the site conditions and the parameters of earthquake history. The study and analysis of seismic and geological environmental conditions of the site are based on epicenter of earthquake, site conditions, and to study the wave propagation, attenuation and seismic liquefaction effects after earthquake form the engineering point of view. The purpose of the paper is to provide basis knowledge for seismic design of engineering structures.This study follows through the study of Yunnan Province Natural Science Foundation project named "GIS-based seismic evaluation and disaster prediction of the road network in Kunming".The present study is focused on seismic hazard analysis of engineering site. The spatial and attribute data of large amount of boring logs are systematic management and analysis engineering site by means of GIS-the powerful spatial data storage and management,the results are visualized by GIS. Finally a seismic hazard analysis system has been developed with the aid of components of Arc Engine which is provided by ArcGIS series software.This paper has developed several modules, including the spatial distribution of seismic liquefaction, site response spectrum characteristic periods and earthquake-affected field generated,etc based on the previous study on seismic hazard analysis system for engineering site. Studies in this paper include the following contents:1. The basic theories and methods of the engineering site seismic hazard analysis;2. Ground motion attenuation model and engineering site seismic liquefaction model;3. The methods of GIS used in engineering site seismic hazard analysis;4. Design and build of engineering site seismic hazard analysis database; 5. Development of the calculate model embedded into GIS systems which has friendly interactive interface,and more intuitive operability;Generally Speaking, GIS-Based seismic hazard analysis system for engineering site can provide reasonable methods for engineering site data storage and management, provide convenient and efficient means for the display of result visualization, provide site information for the city development and provide means for seismic design of engineering structures.更多还原
