Pile capacity in sand — the β-method

What this module covers

• Apply the β-method to compute shaft resistance in sand
• Explain what K and δ each represent, and which one installation changes
• Apply a limiting shaft stress and a limiting base pressure, and state the dispute over both
• Compare the shaft-base split in sand with the equivalent in clay

Lessons
