geofound

A Python package to assess the settlement and bearing capacity of foundations.

How to Use

The geofound package relies on two main Objects, the Foundation object and the Soil object.

These objects are inherited from the sfsimodels python module.

Examples

import geofound
import geofound.settlement
import geofound.capacity


length = 21.7
width = 1.5  # metres
depth = 1.5  # metres
phi = 38
cohesion = 0
unit_weight = 18.5  # submerged
youngs_modulus_soil = 30000


fd = geofound.create_foundation(length, width, depth)
sl = geofound.create_soil(phi, cohesion, unit_weight)

sl.unit_sat_weight = 18.5

q_lim = geofound.capacity.capacity_vesic_1975(sl, fd)
p_max = q_lim * length * width

print(' ')
print('Ultimate bearing stress is q_lim = ' + str(round(q_lim,0)) + ' kPa')
print('Ultimate load is Q_lim = ' + str(round(p_max, 0)) + ' kN')

and for settlement.

load = 21484
s = geofound.settlement.settlement_schmertmann(sl, fd, load, youngs_modulus_soil)
print(' ')
print('Settlement is si = ' + str(round(s,2)) + ' m')
