浸没问题是平原型水库建设的重要问题,科学预测浸没范围对库区范围的确定和移民迁建工作具有十分重要的意义。以淮河出山店水库平昌关地块为研究对象,通过现场工程与水文地质调绘,对地块进行详细勘察,建立地块的三维水文地质模型,不断调整模型边界和参数,对计算模型进行了识别与检验。采用得到的模型与参数对地块进行了三维渗流数值模拟计算分析,并且得到了浸没范围与地表坡降的统计公式,为水库的建设提供了重要的依据。
Immersion is an important issue in the construction of plain reservoirs. It is of great significance for the scientific prediction of the extent of immersion to determine the scope of the reservoir area and relocate and relocate. Taking the Pingshanguan block of the Huashandian reservoir as the research object, the site is reconstructed through on-site engineering and hydrogeology, the three-dimensional hydrogeological model of the block is established, and the model boundary and parameters are adjusted continuously to calculate the model Identify and test. The three - dimensional seepage numerical simulation of the block was carried out by using the model and parameters obtained. The statistical formula of immersion range and slope gradient was obtained, which provided an important basis for the construction of the reservoir.
