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 find hidden dangers of urban underground pipelines, GIS spatial analysis method was used to construct mathematical models of near-line pressure and line pressure occupancy identification in urban underground pipelines, and a technical process of sharing hidden risks was established. According to the comprehensive underground pipeline census data in a certain area of W city, the identification of hidden troubles in the area is carried out. The analysis results are submitted to the corresponding urban planning department for verification in line with the actual situation of the construction of the research area. The analysis results validate the identification model and the validity of the underground integrated pipeline based on GIS, which can provide a scientific basis for the planning and design, safe operation and maintenance of the urban underground pipeline.
