Construction and application of fracture seepage and heat transfer visualization teaching device based on 3D printing technology

针对岩体裂隙复杂多变和模型制作困难的问题,该文将3D打印技术引入实验教学中,构建裂隙渗流与传热可视化实验装置,在不同注入强度和温度条件下,监测、分析裂隙渗流场与温度场时空演化规律。依托于该实验装置,可以突破传统的物理模拟实验思维,以学生自主发现问题为出发点,分组完成裂隙模型设计与制作、实验过程观测与分析、成果汇总与报告,帮助学生全面理解不同裂隙结构条件下渗流场与温度场特征,锻炼学生理论联系实际的能力及创新思维。

In view of the complexity of rock fractures and the difficulty of model making,3D printing technology is introduced into experimental teaching to construct a visualized experimental device for fracture seepage and heat transfer.The temporal and spatial evolution of fracture seepage field and temperature field is monitored and analyzed under different injection intensities and temperatures.Relying on this experimental device,we can break through the traditional physical simulation experiment thinking,take students’independent discovery of problems as the starting point,complete the design and production of fracture model,observation and analysis of experimental process,summary and report of results in groups,help students fully understand the characteristics of seepage field and temperature field under different fracture structure conditions,and exercise students’ability of combining theory with practice and innovative thinking.
