WebJul 10, 2024 · In summary, it can be seen that under different wall friction coefficients, the time when the whole soil-rock mixed accumulation body starts to fail and slide is nearly the same. This is mainly because the changed parameter is the friction coefficient of sliding wall, so the state before instability is basically the same.
