Interaction of Compaction Piles with Surrounding Soil with Due Regard for Pile Diameter Expansion

Аннотация

Analytical and numerical solutions are provided for the problem of the interaction between compaction piles and a foundation slab and a surrounding soil cylinder that rests on an incompressible bed, with due regard for the potential expansion of the pile shaft. Closed solutions are obtained for determining stresses in the pile shaft and the soil under a foundation slab in an end bearing pile scheme. This issue is most immediate for transforming beds using drain piles composed of a sand-gravel mixture.
