Turbo-generator machines while operation generate harmonic load on the foundation which may create heavy vibration in case it's not considered in the foundation design. The present work studies the effect of raft, pile with raft and barrettes with raft subjected to harmonic load on the turbo-generator foundation in medium dense and partially saturated sand.

Soil mechanics - Wikipedia

Soil mechanics is a branch of soil physics and applied mechanics that describes the behavior of soils. It differs from fluid mechanics and solid mechanics in the sense that soils consist of a heterogeneous mixture of fluids (usually air and water) and particles (usually clay, silt, sand, and gravel ) but soil may also contain organic solids ...
