摘　　要：目前,GIS对多源地学信息进行综合分析,广泛应用于地质、环境等研究领域。通过分析我国岩土工程的现状和GIS在岩土工程中应用的情况,阐述GIS技术在岩溶地区渣场的应用状况,通过对磷石膏堆填体的位置形态、渣场的面积、体积、任意点磷石膏厚度等进行节理裂隙分析;根据节理裂隙分析结果进行三维建模,分析岩体结构面的空间形态、组合关系、分布和延展规律等。判断结构面发展趋势,从而分析地下水在结构面中的运动方向,判断磷石膏渣场在基岩中的流向,为治理地下水提供科学依据。At present,GIS for multi-source geo-information to make a comprehensive analysis is widely used in geological and environmental research.Through the analysis of the current situation and GIS applications in geotechnical engineering,with a description of the GIS technology application in the Karst area,and the location of the landfill body shape,area,volume,the thickness of any point of phosphogypsum and so phosphogypsum jointed analysis;three-dimensional modeling based on the results of jointed analysis,analysis of rock mass structure of the space form of the relationship between composition,distribution and the extension of law and so on.Development trends to determine the structure surface,thereby to analyze the structure of the groundwater surface in the direction of movement to determine phosphogypsum slag field of flow in the bedrock,to provide scientific basis for groundwater management.
