Question

Types of soil retaining structures which is most suitable for saturated gravelly soil

Answer 1

Soil has two main properties that are used to determine how much reinforcement is required to stabilize a soil mass. The internal strength, soil friction angle or Phi angle, of different soils plays a major role in determining how well soils hold themselves up. This internal strength of the soil, not the retaining wall, performs most of the work of holding up any hillside. The friction angle of the soil is an indi- cator on how well the soil will support
