下渗实验与井流实验是水文地质学科专业基础教学的重要实践内容,灵活开展定水头、变水头下渗及潜水、承压水井流实验是对本科生专业技能训练的基本要求.由于实验设备与空间不足,在有限学时内,无法为学生呈现完整的实验过程,且渗流运动发生于看不见摸不到的地面以下,对其理解具有一定难度,制约实验教学效果.为此,设计包气带—饱和带渗流运动模拟虚拟仿真实验平台,涵盖实验导学、下渗实验与井流实验等主要环节,重点模拟包括野外样品采集与理化性质测试、装填土柱等基本实验操作环节,同时拓展降水条件下,野外变水头下渗及井流过程的交互式虚拟仿真实验.通过可视化的仿真结果,帮助学生理解下渗及井流过程,为提升水文地质专业实践教学效果提供了一种有效途径.
Design and Implementation of Virtual Simulation Platform for Seepage Flow Motion Simulation
Infiltration experiment and well flow experiment are important practical contents to support the basic teaching of hydrogeology.It is the basic requirement for undergraduates'professional skills to flexibly design and carry out infiltration experiments with constant head and variable head,as well as unconfined aquifer and confined aquifer water well flow experiments.However,in view of the lack of experimental equipment and space,the whole process of the experiment cannot be completely presented within the limited class hours,and the seepage movement occurs below the invisible ground.It is difficult to understand and master it,which restricts the effect of experimental teaching.Therefore,a virtual simulation experiment platform for vadose zone and saturated zone seepage motion simulation is designed,which covers four main links,i.e.,experimental guidance,experimental purpose,infiltration experiment and well flow experiment.The key simulation includes basic experimental operation links such as field sample collection and physical and chemical properties test,loading soil column,etc.At the same time,the interactive virtual simulation operation links of field variable head infiltration and well flow process under precipitation conditions are expanded.Through the visual simulation results,it is relatively easy to understand the infiltration and well flow process,which provides an effective way to improve the practical teaching of hydrogeology.
