摘要
本文在大量实际调查的基础上，采用有限元、模糊信息分析、灰色理论、土动力学试验以及工程地质分析等手段对西安市的地质灾害（如地震动、地裂缝、地面沉降、砂土液化、黄土震陷以及人工填土和软弱土层的危害等）进行了深入研究。评价出了各种灾害的程度并对其进行模糊信息统一处理，然后评价出总的灾害程度。据此将西安市接０．２５ｋｍ×０．２５ｋｍ划分成网络单元，按每个网络单元的总灾害程度编制出西安市综合地质灾害分区图。
In this paper data from practical inrestigations and laboratory tests are combined.The synthetical geological hazards of Xian City,including ground motion,ground fissures,earth subsidonce,sandy soil liquefaction,loess seism-sinkage and damage of artificial filled soil,have been considered.At first,the degrees of various geological disasters were evaluated and calculated by using a new theory and method.Secondly,we combined the evaluated results of varied hazards by using fuzzy information analysis and establised the total hazard degree by using the finite element technique and method of fuzzy information analysis.Finally.Xian was divided into 8320(0.25km×0.25km)units and total hazards degree of each unit was determined from these results,A map of synthetical geological hazards was made.
