Abstract EN
The deformation and failure characteristics of deep rock masses are the focus of this study on deep rock mass engineering.
The study identifies the deformation and failure characteristics of a deep cavern under different ground stress conditions using model test and theoretical analysis methods.
First, the similarity theory for model tests is introduced, and then the scale factors used in the present study are calculated according to the Froude criterion.
Based on the study objectives, the details of the study methods (the similarity coefficient, the loading conditions, the test steps, etc.) are introduced.
Finally, the failure characteristics of the deep cavern and the strain distribution characteristics surrounding the caverns under different ground stress conditions are identified using the model test.
It was found that compared with shallow rock masses the rock masses of the deep cavern have a much greater tensile range, which reaches 1.5 times the diameter of the cavern under the conditions established in the present study.
Under different ground stress conditions, there are differences in failure characteristics and the reasons of the differences were analyzed.
The implication of the test results on the design of support system for deep caverns was presented.
