Worked Example
Verified calculation
Given:
- Rock Load Intensity = 120000
- Tunnel Crown Radius = 3
- Shotcrete-Rock Bond Strength = 1000000
Expected Result:
- Required Shotcrete Thickness = 0.18
Engineering Interpretation:
Under the given input conditions, the calculated result is: Required Shotcrete Thickness = 0.18 m.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.
Formula / Method
required shotcrete thickness = (rock load intensity * tunnel crown radius) / (shotcrete-rock bond strength * 2.0)Formula family: formula_tunnel_shotcrete_thickness_calculator_based_on_rock_load_and_bond_strength
