为了辨识和发现城市地下管线占压隐患,采用GIS空间分析方法,构建了城市地下管线近线占压和压线占压识别数学模型,建立了占压隐患分析的技术流程.结合W城市某区域的综合地下管线普查数据,进行了该区域的占压隐患辨识,分析结果提交相应城市规划部门,经核实符合研究区建设发展实际情况.分析结果验证了基于GIS的地下综合管线占压辨识模型、流程的有效性,可为城市地下管线的规划设计、安全运营、维修维护提供科学依据.%In order to identify and discover the occupying potential hazard of urban underground pipeline,a mathematical model on identification of the near pipeline and over pipeline occupying for urban underground pipeline was constructed by u-sing the GIS spatial analysis method,and the technical procedure of occupying potential hazard analysis was established. Combined with the survey data of underground integrated pipelines in a certain region of W city,the identification of occup-ying potential hazard in this region was carried out,and the results were submitted to the corresponding urban planning de-partment,which were in accordance with the actual situation of construction and development in the studied region after veri-fication. The analysis results verified the effectiveness of the model and procedure of occupying identification for underground integrated pipelines based on GIS. It can provide scientific basis for the planning and design,safe operation,servicing and maintenance of urban underground pipelines.
