In this article, the authors present a laboratory experiment, which was conducted with postgraduate students in the Research and Production Center ENU-Lab at L.N. Gumilyov Eurasian National University, Astana, Kazakhstan. The originality of the experiment lies in the combination of experimental modelling of subsidence soil and in determining the peculiarities of changes in strength and deformation properties in soil bases reinforced by geosynthetics. This experiment allows students to practice skills in geological investigations through the assessment of soil collapsing. A test programme and a compression apparatus manual have been developed to help students cope with the task. Upon completion, the students presented a comparative analysis of the data and plotted the dependence of changes in the height of the specimen on the load, and determined the coefficient of collapsing before and after reinforcement. The experimental activities of students during the experiment were also evaluated and compared with the aim of planning additional express courses to improve the quality of knowledge and skills.
