Retaining Wall Seepage Uplift Foundation Package

Calculates source-bound retaining wall metrics from a deterministic SSC-07 task-owned source pack. The template combines lateral pressure, wall sliding and overturning, bearing pressure, exit gradient, and uplift checks for one retaining section.

with-tool: The model is given an executable Python calculator script.

Difficulty

Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.

All inputs remain visible at every tier

For this template, difficulty scales through parameter and scenario ranges rather than hidden information.

All source-pack values given for the SSC-07 retaining wall seepage package
medium:
All source-pack values given for the SSC-07 retaining wall seepage package
