2. Discrete element numerical simulation of geological (geotechnical) engineering.
The extraction of microstructure in the process of sand compression is helpful to understand its microstructure mechanism in compression deformation and failure.By improving the existing consolidation instrument, the extraction of microstructure in the process of sand compression was realized, and PCAS was used for quantitative analysis of microstructure.It is used to study the microscopic mechanism of land subsidence.
