摘要
"地下水动力学"是一门专业核心课程,在地下水科学与工程专业培养方案中占有重要地位。地下水动力学实验则是地下水动力学课程的实践性环节,是不可或缺的重要教学内容。丰富地下水动力学实验的内容是提高教学质量和深化教学改革的关键。抽水实验是地下水动力学实验重要的内容之一,野外开展抽水实验具有耗时长、现象不直观等缺点,为此研制了一种承压井抽水动态实验仪,可在室内开展试验,观察抽水过程中的地下水运动状态和动力特征。该文介绍了仪器的结构、功能和工作原理,分析了实验现象。相比以往的地下水动力学实验教学内容,该实验仪纳入实验教学内容具有重要意义,为推动我校地下水科学与工程专业的教学改革起到了重要促进作用。
"Groundwater hydraulics"is a professional core course,which plays an important role in the training program of groundwater science and engineering.The experiment of groundwater hydraulics is a practical link of groundwater hydraulics course and an indispensable important teaching content.To enrich the content of the experimental groundwater hydraulics is the key for enhancing the teaching quality and the deepen informing and innovation.Pumping experiment is one of the most considerable contents included in the experimental groundwater hydraulics.The pumping experiment in the field has the disadvantages of long time-consuming and non-intuitive phenomenon.Therefore,the laboratory has developed a pumping dynamic experimental instrument for confined wells,which can be carried out in the laboratory to observe the groundwater movement state and dynamic characteristics during the pumping process.This paper introduces the structure,function and working principle of the instrument,and analyzes the test phenomenon.Compared with the previous teaching contents of groundwater dynamics experiment,it is of great significance to bring the newly developed pumping dynamic experimental instrument of confined well into the experimental teaching content,which plays an important role in promoting the teaching reform of groundwater science and engineering specialty in the university.
