Taiwan has a diverse geological environment caused by plate movement. On average, there are about 26,686 earthquakes per year in Taiwan, and this fact leaves the rock slopes in an unstable state, not to say the influence caused by the heavy rainfall.
Because of the need to explore the stability and failure mechanism of rock slopes with different scales, the laboratory tests with centrifuge in NCU were conducted to simulate simplified models to record the rock slope behavior under different layer thickness with 5mm diameter grinding stone ball. Detailed analysis was performed on the simulated results to obtain the deformation of each piece of rock sheet and the overall failure deformation ratio.
Afterwards, we have used PFC3D to simulate the same model in centrifuge test with the same gravitational field. First of all, numerical simulations were verified by comparing to physical simulations. Secondly, we used the verified numerical parameters to run the numerical models with 100g, simulating anti-dip slopes with 7.5 to 12 meter height and discussed the deformation and failure results under this numerical simulation result. |
