【摘要】：水问题已成为21世纪威胁世界和平、威胁人类生存和生态安全的首要因素,水利是国民经济的基础产业,水资源作为国民基础生产中的重要自然资源和不可或缺的经济资源,在国民经济中占有举足轻重的经济发展地位,同时也是当代生态环境重要组成部分,在当代国家发展中具有重要的战略地位。为解决我国水资源分布不均的现实状况,通过大中型水利工程实现水资源调配是我国目前水利建设的重要策略。中华人民共和国成立以来,经过半个多世纪的建设与发展,水利工程建设取得了巨大成就,尤其是担负调峰、调频、防洪、灌溉、航运及工业和居民用水等特殊功能和任务的水库工程建设,为中国的现代化建设提供了强大的安全防汛和水资源利用保证。但是,洪涝灾害、干旱缺水、水土流失和水污染等四大问题还远没有解决,每年带来的损失也越来越巨大,水资源与国民经济和社会发展不适应的矛盾越来越突出,已经严重影响全面建设小康社会目标的实现。经济的现代化离不开水利现代化的保障,努力探索和实践适应社会主义经济发展的现代水利是水利工作者义不容辞的责任。面对严峻形势,应用现代科学理论和高新技术,对水利工程实行科学管理,确保对水资源的合理开发、高效利用、优化配置、全面节约、有效保护和综合治理,用水利信息化来带动水利现代化已经成为中国21世纪水利事业发展的必然。水库的安全高效率运行是保障水资源合理开发利用的基础。洪水作为威胁水库和下游人民财产安全的重要因素,同时也是宝贵的水资源,如何在保证大坝安全的前提下尽可能的利用洪水资源,尽可能多发挥洪水的利用率成为关键的问题。建立一套合理的洪水预报体系和大坝安全监测平台为上级决策提供便利很有必要。基于以上分析和认识,本论文的主要研究内容如下:(1)分析该流域的水文资料,选择国内较为成熟的水文预报模型对其产流机理进行分析。(2)对流域进行单元划分,分析降雨量,蒸发量,河道入流资料,分别建立新安江模型和双超模型,在该流域对其进行参数优化,使其得到较为满意的预报信息。(3)分析大坝的具体情况,优化测压管管线布置,对大坝测压管进行冲洗处理,通过测试表明其灵敏度合格,为大坝渗流监测系统打下基础。(4)完成信息采集系统的硬件选型,及构建监测硬件的信息传输系统的通讯组网的设计研究,实现监测数据的即时采集、分析、传输、展示和应用。通过统计回归模型对采集回来的数据进行分析,以判别大坝的安全性。(5)通过对改流域洪水两种模型的预报,结合大坝安全监测系统编写了水库综合自动化系统软件。渗实现数值模拟结果与SQL、VB、Excel等常用软件的无缝链接。洪水预报和大坝安全监测是水库综合自动化系统中的重要组成部分,但对于水库水资源调度以及视频监控问等,须要做更深一步研究。
[Abstract]:In 21th century, water problem has become the most important factor threatening world peace and human survival and ecological security. Water conservancy is the basic industry of national economy. Water resources are important natural resources and indispensable economic resources in national basic production. In order to solve the problem of uneven distribution of water resources in China, it plays an important role in economic development in the national economy, and is also an important part of the contemporary ecological environment, and plays an important strategic role in the development of contemporary countries. The allocation of water resources through large and medium-sized water conservancy projects is an important strategy for water conservancy construction in China. Since the founding of the people's Republic of China, after more than half a century of construction and development, great achievements have been made in the construction of water conservancy projects. In particular, reservoir construction, which has special functions and tasks such as peak-shaving, FM, flood control, irrigation, shipping, industrial and residential water use and other special functions and tasks, has provided a strong guarantee for the modernization of China in flood prevention and water resources utilization. The four major problems of flood disaster, drought and water shortage, soil erosion and water pollution are still far from being solved, and the losses caused by each year are becoming more and more enormous, and the contradiction between water resources and the unsuitable development of the national economy and society is becoming more and more prominent. It has seriously affected the realization of the goal of building a well-off society in an all-round way. The modernization of the economy cannot be separated from the guarantee of the modernization of water conservancy. It is incumbent on water conservancy workers to explore and practice modern water conservancy projects that adapt to the development of socialist economy. In the face of the severe situation, applying modern scientific theory and high and new technology to the scientific management of water conservancy projects, To ensure the rational development of water resources, efficient utilization, optimal allocation, comprehensive conservation, effective protection and comprehensive management, Using water conservancy information to drive water conservancy modernization has become a necessity for the development of water conservancy in 21th century in China. The safe and efficient operation of reservoir is the basis to guarantee the rational development and utilization of water resources. Flood is a threat to reservoir and downstream. Important factors for the safety of people's property, At the same time, it is also a valuable water resource. How to make use of flood resources as far as possible under the premise of ensuring dam safety, Maximizing flood utilization is a key issue. It is necessary to establish a reasonable flood forecasting system and dam safety monitoring platform to facilitate superior decision-making. Based on the above analysis and understanding, The main contents of this paper are as follows: (1) analyzing the hydrological data of the basin, selecting the more mature hydrological forecasting model in China to analyze the mechanism of runoff generation. The Xinanjiang model and the double supermodel are established respectively. The parameters of the dam are optimized in the basin to obtain satisfactory forecast information. The concrete situation of the dam is analyzed, the layout of the pressure measuring pipe is optimized, and the pressure measuring pipe of the dam is flushed out. The test shows that its sensitivity is up to standard, which lays the foundation for dam seepage monitoring system. It completes the hardware selection of information collection system and the design of communication network for constructing information transmission system of monitoring hardware. To realize the real-time collection, analysis, transmission, display and application of monitoring data. Through the statistical regression model, the collected data are analyzed to judge the dam safety. Combined with dam safety monitoring system, the software of reservoir integrated automation system is compiled. The results of seepage numerical simulation are seamlessly linked to the common software such as SQL VBX Excel. Flood forecasting and dam safety monitoring are important parts of reservoir integrated automation system. However, more research is needed for reservoir water resource regulation and video surveillance.
