NUMERICAL ANALYSIS OF THE ELASTOPLASTIC FAILURE PROCESS OF THE SURROUNDING ROCKS OF UNDERGROUND CAVERNS
The elastoplastic failure process of the surrounding rocks of underground cavern is studied in this paper, which is based on the self-developing Rock Elastic-Plastic Failure Process Analysis code (REPFPA). With this numerical tool, numerous numerical tests are earned out, and it is shown that there is a relationship between the shape of cavity and the limit bearing capacity of surrounding rocks. These identifications are crucial for better understanding and interpreting the experimental results and will consequently improve our concepts in the design or analysis of the underground engineering structures.
