【摘要】：随着我国经济发展步伐的逐渐加快,城市化进程也在飞速推进。随之而来的是城市基础设施不足或滞后问题。其中排水管网规划建设问题尤为突出,具体表现为近年来城市暴雨常常导致的城市“内涝”,影响城市的交通、生产,甚至威胁到居民的人身安全。要解决这一问题除了加大投资以外,更主要的是相关的规划与管理部门必须很好地处理“规划、设计、建设、运行”与城市排水需求之间的矛盾。传统的“一个文本,一张蓝图”式的规划,由于无法适应排水需求的急剧变化,已经不能满足我国当前的社会经济快速发展对排水管网规划的需求。同时,随着我国的排水管网规划技术和理念的不断更新,GIS技术、动态规划、分期建设等新的规划技术和规划理念被引入。论文针对传统规划方法不能有效解决供需矛盾,在分析目前国内外最新的排水管网规划设计软件缺陷的基础上,深入贯彻“动态规划”和“分期建设”两个重要的最新规划理念,剖析当前建设资金有限的情况下面临的排水需求激增的问题,在现有基于GIS的排水管网规划软件功能的基础上,融入大量智能化分析与决策支持模块,更加充分地利用GIS平台强大的地理信息数据管理能力和空间查询及运算能力,开发出一套基于GIS的城市排水管网动态规划管理评价系统(EasyPlanning)。论文主要包含以下几方面内容： ①在系统开发之前,主要围绕“水量预测模型”、“管网评价模型”以及“分期建设实现方法”三方面进行了详细的研究,切合计算机和GIS平台的特点,分析了管网规划者在这三方面的具体功能需求,最终确定了模型的具体算法和具体实现方法,为后续系统的开发奠定了研究基础。 ②构建系统数据存储所用的Personal GeoDatabase,设计数据的结构和必要要素的字段规范与编码规范等。同时,搭建好EasyPlanning系统的界面外观、功能框架以及数据流等。 ③在前面基础工作之后,逐步开发并完善EasyPlanning系统的功能模块及具体工具等,对完成的代码进行测试、反馈、改进,力求让执行效率和用户体验达到最佳。 ④选取典型案例,在EasyPlanning系统上进行规划,并将得到的规划方案与实际方案进行对比分析。将案例应用的效果、对比分析的结果进行反馈总结,进一步改进、完善系统。
[Abstract]:With the gradual acceleration of the pace of China's economic development, the process of urbanization is also advancing at full speed. The following is the lack or lag of urban infrastructure. The problem of drainage network planning and construction is especially prominent, which is manifested in the urban "waterlogging" which is often caused by urban rainstorm in recent years, which affects the traffic, production and even threatens the personal safety of the residents. In order to solve this problem, besides increasing investment, the related planning and management departments must deal well with the contradiction between "planning, design, construction and operation" and urban drainage demand. The traditional "one text, one blueprint"-style planning can not meet the demand of drainage network planning for the rapid development of social economy in our country because it can not adapt to the rapid change of drainage demand. At the same time, with the continuous updating of the drainage network planning technology and concept in China, new planning techniques and concepts such as GIS technology, dynamic planning, phased construction and other new planning techniques and concepts have been introduced. In view of the traditional planning method can not effectively solve the contradiction between supply and demand, based on the analysis of the latest domestic and foreign drainage network planning and design software defects, In-depth implementation of the "dynamic planning" and "phased construction" two important latest planning concepts, to analyze the current construction funds are limited to face the problem of rapid demand for drainage, On the basis of the functions of the existing drainage network planning software based on GIS, a large number of intelligent analysis and decision support modules are incorporated to make full use of the powerful ability of geographic information data management and spatial query and operation of the GIS platform. A set of dynamic planning management evaluation system (EasyPlanning).) for urban drainage network based on GIS is developed. The thesis mainly includes the following aspects: (1) before the system development, it mainly focused on the three aspects of "water forecast model", "pipe network evaluation model" and "realization method of phased construction". According to the characteristics of computer and GIS platform, this paper analyzes the specific functional requirements of pipe network planners in these three aspects, and finally determines the specific algorithm and implementation method of the model, which lays a foundation for the development of the subsequent system. (2) the structure of the Personal GeoDatabase, design data and the field specification and coding specification of the essential elements used to construct the system data storage. At the same time, build EasyPlanning system interface appearance, functional framework and data flow. 3After the previous basic work, we gradually develop and perfect the functional modules and specific tools of the EasyPlanning system, test, feedback and improve the completed code, and strive to achieve the best execution efficiency and user experience. (4) A typical case is selected to plan on the EasyPlanning system, and the scheme is compared with the actual one. The effect of the application of the case, comparative analysis of the results of feedback summary, further improvement, perfect the system.
