抽水试验是野外完成的重要的水文地质试验。为了让水文专业及地质专业的学生在室内真正体验到抽水试验的过程及细节,作者试制了一种可实现三维水位观测的抽水试验实验教学装置。该装置可实现不同条件的抽水试验:均质非均质、各向同性与各向异性、不同补给与排泄边界等等,并可以获得实时三维水位动态观测数据。该装置既解决了抽水试验实践性教学环节在室内进行的问题,也能完成一些科学试验。多年来的教学实践证明效果显著:通过这样的试验,同学们既掌握了水文地质调查工作中抽水试验的要领,又对地下水流理论有了进一步的理解。
Pumping tests are important hydrogeological tests done in the field. In order to let the aquatic professional and geology students truly experience the pumping test process and details indoors, the author experimented with a pumping experiment experiment teaching device that can realize the three-dimensional water level observation. The device can be used to carry out pumping tests under different conditions: homogeneous heterogeneity, isotropy and anisotropy, different supply and discharge boundaries, and the like, and real-time three-dimensional water level dynamic observation data can be obtained. The device not only solves the problem of practicing the pumping test indoors, but also can accomplish some scientific experiments. The teaching practice over the years has proved to be very effective. Through such experiments, students have mastered the essentials of pumping tests in hydrogeological investigations and have further understanding of the theory of groundwater flow.
