Retaining Wall Bearing Safety Calculator
Bearing capacity/actual independently established maximum contact pressure, not wall sliding or bearing-capacity derivation. Actual independently established compatible SI units/model context; conditional arithmetic, not code compliance, engineering design or safe operation approval.
Description
A bearing ratio compares independently verified bearing capacity with an established maximum contact pressure.
A bearing ratio compares independently verified bearing capacity with an established maximum contact pressure.1
This tool calculates the ratio without deriving capacity or assessing wall sliding and overturning.
When to use Retaining Wall Bearing Safety Calculator
Use this tool to calculate the ratio without deriving capacity or assessing wall sliding and overturning.
How to use Retaining Wall Bearing Safety Calculator and how it works
- Prepare callerIndependentlyVerifiedBearingCapacity, actualMaximumBasePressure, with the units, conventions and assumptions below.
- Enter the required fields and run Retaining Wall Bearing Safety Calculator.
- Read result.value using the output definitions below.
- Correct any rejected inputs and rerun; interpret the result within the stated model and its assumptions.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerIndependentlyVerifiedBearingCapacity | Caller Independently Verified Bearing Capacity. Use the units and matching context stated in the calculation below. | number | Required; strictly positive; finite; other constraints below |
| actualMaximumBasePressure | Actual Maximum Base Pressure. Use the units and matching context stated in the calculation below. | number | Required; strictly positive; finite; other constraints below |
Supply positive applicable bearing capacity and positive independently established maximum base pressure in the same unit. Return capacity/pressure as a dimensionless ratio. Eccentricity, sliding, overturning and the adequacy of the chosen bearing criterion are not assessed.
bearingSafetyRatio=bearingCapacity/maximumBasePressure Apply the input ordering, units and branch conditions stated above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the calculated or selected fields below. | object |
| result.value | Dimensionless bearing-capacity to maximum-pressure ratio. | number |

}Limitations and assumptions
The calculation uses the supplied observations and model inputs. It does not collect measurements, select a reference population or coefficient, or establish that the model applies to the actual case. The stated branch conditions and output units remain part of the result.
All fields require explicit values. Unexpected fields, wrong types, nonfinite numbers and sparse arrays are rejected. Alignment, bounds and supported-token rules are explained above; extremely large inputs or nonfinite results can also fail. Input errors differ from successful false comparisons, unavailable-domain flags and empty match lists.
Alternative or Complementary methods
Use Janbu Slope Stability Calculator for a complementary operation: Janbu slope analysis depends on slice geometry, pore pressures and an explicitly chosen equilibrium convention.
Use Caisson Bearing Calculator for a complementary operation: Caisson bearing depends on soil, embedment, water and loading under an independently validated method.
