《地下工程监测与检测》是一门实践性非常强的课程，实验环节是该课程教学非常必要的部分。然而，真实的地下工程现场监测实验耗时耗力，开展难度大、风险系数高；而模型箱实验又与工程实际相差较远。本文给出一种模拟实验的教学设计，充分利用大学校园空地和实验室现有实验设备，通过简化改进标准实验步骤，设计了超载下土压力测试和平板载荷现场模拟实验。教学实践表明，学生能据此完成实验基本操作，取得了符合规律的实验数据，教学效果良好。基于模拟实验步骤开展实验环节教学，既有利于学生掌握实验原理，了解地下工程现场监测的实况，又充分保障了师生安全，是开展该课程实验环节教学较好的设计思路。
Testing and Inspect of Underground Engineering is a practical discipline, and the experimental teaching is an essential part of this course. However, the actual in-situ underground monitoring and inspecting tests are generally difficult to conduct on campus, since they are always laborious, time-consuming, and withstand high-risks. Meanwhile, the model box experiments are so far from the engineering reality. Consequently, this paper proposed a simulated test design in the experimental teaching. By simplifying the standard testing steps, two simulated test design cases of Soil Pressure Test under preloading and Plate Loading Test (PLT) are presented in detail, making good use of open space on the campus and the available testing equipment in our lab. The teaching practice shows that, good teaching result could be achieved through applying the designed teaching process; following the experimental steps of the simulated test design, students could smoothly accomplish the two tests, and obtain testing data with rather good quality. It leads to several benefits to conduct the experimental teaching according to the designed simulated experimental procedures, including enhancing students’ understanding of the experimental principles, obtaining vivid feeling of how in-situ tests are conducted, and ensuring the safety of the students and teachers in the testing, etc. All in all, it is an effective way to conduct the experimental teaching according to the proposed simulated test design.
