摘要
应用GIS技术,以MapInfo为操作平台,对淮安市区潜在的场地地震液化性能进行了综合的分析和评估,建立了场地土壤液化的数据资料库,并以此为背景,建立了潜在液化分析评估系统,对场地地震液化的危害性进行了分析和评估。研究表明,将GIS技术引入到场地地震液化风险评估中,可以方便数据的输入、管理、查询和分析,使场地地震液化风险评估结果能以直观的地图形式显示出来,便于决策部门做出快速、有效的判断。
This paper uses GIS technology and MapInfo to synthetically analyse the potential risk of sandy soil liquefaction of the ground in Huai′an City and the database systems of sandy soil liquefaction also has been built up. Regard the database as the background, the evaluation system for potential sandy soil liquefaction was established that the hazard of sandy soil liquefaction of the ground can be analyzed and evaluated. The research shows that introduction of GIS technique into the evaluation of potential risk of earthquake-induced sandy soil liquefaction of the ground not only can convenience the input,management,inquiry and analysis of the data, make the results directly displayed in the forms of maps, convenience the fast effective judgements of decision making body.
