In a pile foundation, load transfer to the surrounding soil may occur through:
Correct answer: C. End bearing and shaft friction
- A. Only soil suction
- B. Only capillary pressure
- C. End bearing and shaft friction
- D. Buoyancy and surface tension
Explanation
A pile can transfer load at its tip by end bearing and along its embedded surface by shaft friction. The relative contribution depends on the pile type and the surrounding soil conditions.

About Soil Mechanics and Foundations
Soil mechanics examines index properties, phase relationships, classification, permeability, seepage, compaction, consolidation, shear strength and earth pressure. Foundations apply these principles to bearing capacity, settlement and shallow or deep foundation selection, with clear distinction between compaction, which expels air, and consolidation, which expels water over time.
