【摘要】：水能是一种无污染、可再生、运行费用低的清洁能源。水能发电便于电力调峰，能够提高资源利用率和经济社会的综合效益。面对地球传统资源日益紧张趋势，世界各国纷纷优先选择和大力开发利用水能资源。目前，水能发电作为电力行业中最重要的清洁能源和可再生能源之一，发展的潜力巨大。我国已探明的水能资源蕴藏量和可能开发的水能资源量都位居世界第一，也是目前世界上建设规模最大、水电装机容量最多和发展速度最快的国家。沾河海拨高程100m～700m，河流全长250km，流域面积6551km2，，水能开发潜力巨大。因此，有必要在沾河选择建坝条件较好的河段建立水坝。本文将针对沾河中游河段干流的水能开发进行规划研究，主要开展三方面研究：一是沾河干流工程地质条件勘察与分析，规划河段内出露的主要地层为古生界二迭系地层和中生界侏罗系地层及新生界第三系与第四系地层；侵入岩主要为华力西早期侵入岩和华力西晚期侵入岩及印支期侵入岩。二是沾河干流大坝施工用建筑材料勘查与分析，主要对各规划梯级方案中水电站水库区、坝址、引水建筑物、厂房等工程地质条件进行深入勘查和调研，对砂砾石料、土料等天然建筑材料的产地进行了普查，最后得出客观合理的沾河中游河段干流各水电站区域的地质、地震、工程地质结论，为科学合理开发沾河干流水能提供可靠和宝贵的基础资料。三是沾河干流水能开发方案选择，拟定三个梯级开发方案，分别为二级开发方案、三级开发方案及四级开发方案。二级开发方案，由沾北水电站、新鄂水电站组成；三级开发方案，由沾北水电站、义气敏水电站、新鄂水电站组成；四级开发方案，由都鲁河口水电站、沾北水电站、义气敏水电站、新鄂水电站组成。
[Abstract]:Water energy is a kind of clean energy without pollution, renewable and low operating cost. Water power generation is convenient for power peak adjustment. It can improve the utilization of resources and the comprehensive benefits of economy and society. In the face of the increasingly tense trend of the earth's traditional resources, all countries in the world have chosen and vigorously developed the resources of water energy. At present, the hydropower generation is used as the power industry. One of the most important clean and renewable energy sources has great potential for development. Our country's proven water resources and potential water resources are the first in the world, and the largest country in the world, with the largest capacity and the fastest development speed in the world.
Zhanhe sea allocates 100m ~ 700m, the total length of the river is 250km, the area of the river basin is 6551km2, and the potential of water energy development is great. Therefore, it is necessary to establish the dam in the river section with the better condition of selecting the dam in the river.
In this paper, the water energy development of the main stream in the middle reaches of Zhan He River will be studied in three aspects: first, the investigation and analysis of the geological conditions of the Zhan River main stream, the main strata exposed in the river section are the two superposition strata of the Paleozoic and the Mesozoic Jurassic strata and the third and Quaternary strata of the new birth boundary, and the intrusive rock owners. Two is the exploration and analysis of the construction materials for the construction of Zhan he main stream dam, and the geological conditions for the hydropower station reservoir area, the dam site, the diversion building, the factory building and other engineering geological conditions are carried out in depth. According to the survey of the producing area of the building materials, the objective and reasonable geological, earthquake, and engineering geological conclusions of the area of the main stream of the middle reaches of the river in the middle reaches of the river are obtained, which can provide the reliable and valuable basic data for the scientific and rational exploitation of the dry water of the river, three is the selection of the water energy development scheme of Zhan He River, and the three cascade development schemes are drawn up. Not for the two level development scheme, three level development scheme and four level development scheme. The two level development scheme is composed of die North hydropower station and new Hubei hydropower station; the three level development scheme is composed of die North hydropower station, Yi Qi Min hydropower station, and new Hubei hydropower station; the four level development scheme is made up of the Du Lu River mouth water power station, the Zhi Bei hydropower station, the Yi gas sensitive hydropower station, the new Hubei hydropower station. The station is made up.
