What Can You Do With Bubble 3D?

• View stress distribution under the footings (i.e. stress bulbs),
• Define a stress cut-off (e.g. 20%) for stress bulbs, in order to investigate stress influence zone,
• Investigate the overlap of stress bulbs for adjacent footings,
• Cut through the stress bulb at any location and in any angle,
• Visualize the settlement of the ground surface,
• Various type of footings are covered: pad, strip, circular, raft, ring, box, etc.
• View stress distribution for all soil elements in a tabular format,
• Export the results to image and Microsoft Excel formats

Stress Analysis Methods

Bubble 3D covers the following stress and settlement analysis methods:

• Boussinesq (1885), Holtz and Kavocs (1981)
• Westergaard (1938)
• Newmark (1935)
• 2:1 Method

Settlement Estimation Methods

This program covers various methods for calculation of settlement at each soil element:

• Rigid (semi-infinite)
• Flexible (semi-infinite)
• Elasticity Theory

For more details please see Bubble 3D documentation.

For Educational Purposes

Bubble 3D is designed as a tool for assisting geotechnical engineers to exercise stress distributions specially when there are other surcharges / footings close to a footing. Bubble 3D does not utilize FEM or similar methods; instead, it follows a simple philosophy: It discretizes the model into many ‘soil elements’, and calculates the stress increase due to all surcharges at each soil element, and presents the results graphically.

Bubble 3D is a powerful software for both academia and consulting engineers.
