Grain, Soil and Water Pressure: Testing Risk of Bursting Flashcards
1
Q
How is the risk of bursting assessed?
A
By ensuring:
𝐺>1.1×𝑃
Where:
𝐺=Weight of the soil mass (kN/m²)
𝑃=Groundwater pressure (kN/m²)
If: 𝐺 is too low, failure occurs

Q
Q: What is the failure mechanism for groundwater bursting?
A
If equilibrium is not maintained, impermeable layers crack, allowing uncontrolled water flow into excavations.
