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.
