摘要
辐射井广泛应用于中国西北干旱地区,能够有效解决傍河地区的取水问题。通过大型砂槽物理实验,对现有辐射井取水的数值计算模型进行拟合。在模型合理可靠的基础上,以洛河金鼎水源地为研究区,设计了不同的方案,对辐射管的仰角、长度、竖井位置、河流深度、辐射管埋深等影响因素进行模拟,讨论了不同影响因素下辐射井取水量的变化,并给出了辐射井结构的优化建议,这对辐射井的实际施工具有重要的意义。
Radiation wells are widely used in the arid regions of northwest China,and the installment of these wells can solve the water intake problems effectively for the areas close to the rivers. The calculation model of the existing radiation well was verified by large sand tank experiments. With this applicable and reliable model,the radiation well water intake of Jinding water source was simulated and calculated,according to which different layout schemes were designed to simulate the influencing factors such as angle,length and buried depth of radiation pipes,position of vertical well and river depth. In addition,the variations of the radiation well water intake under different influencing factors were calculated,and the optimization proposal of the radiation well structure was put forward accordingly. This study can provide some reference for the actual construction of radiation wells.
