The study looked at how coarse-grained soil behaves under different conditions like pressure and shear rates. They found that the pressure around the soil has the biggest impact on its strength. The soil can stretch without breaking, forming a barrel shape. The soil's strength is measured by cohesion and friction angle, which were found to be 20.99 kPa and 22.7° respectively. This research helps us understand how this type of soil moves and breaks, and can help us choose the right conditions for testing it.
