GeotechStaffEngineer

Python toolkit for LLM-based geotechnical engineering agents. 35 analysis modules covering foundations, piles, slopes, seismic analysis, ground improvement, FEM, and more.

Installation

# Core package (numpy + scipy + geotech-references)
pip install geotech-staff-engineer

# With all optional agent libraries
pip install geotech-staff-engineer[full]

# Or install individual extras
pip install geotech-staff-engineer[plot,groundhog,opensees]

Quick Start

from bearing_capacity import Footing, SoilLayer, BearingSoilProfile, BearingCapacityAnalysis

footing = Footing(width=2.0, length=10.0, depth=1.5, shape="strip")
layer = SoilLayer(friction_angle=30.0, cohesion=10.0, unit_weight=18.0, thickness=10.0)
profile = BearingSoilProfile(layer1=layer, gwt_depth=5.0)

analysis = BearingCapacityAnalysis(footing=footing, soil=profile)
result = analysis.compute()
print(result.summary())

Modules

All units are SI (meters, kPa, kN, degrees). Every module returns dataclasses with .summary() and .to_dict() methods for easy LLM integration.
