城市地下排水管道隐患评价探索研究

Research on Evaluation System of Urban Underground Drainage Pipeline——A Case Study of Weinan City

在城市内涝频发、城市水环境恶化的背景下,城市排水管网系统问题不断暴露。本文基于地下管线普查数据成果、基础地理信息数据、城区用地规划数据,结合人口、经济区域面积等社会经济数据探索性地确定了地下排水管道评价指标,并建立了评价模型。最后,以渭南市为例,对其排水管网的现状、结构性隐患管道现状进行了评价分析,发现了城区排水不畅的影响因素,为城区排水管网的规划、建设及后期维护改造提供有力的依据。

In the city of frequent waterlogging,urban water environment in the context of deterioration,urban drainage network system problems continue to be exposed.Based on the r esults of underground pipeline survey data,basic geographic information data,urban land use planning data,combined with the socioeconomic data such as population and economic area,this paper explores the evaluation index of underground drainage pipeline and establishes the evaluation model.Finally,taking Weinan City as an example,this paper analyzed the status quo of drainage network and hidden pipeline.It is found that the impact factors of poor urban drainage,which can provide a strong basis for planning,construction,maintenance and transformation of urban drainage network.
