Upload NowIn this article we have compiled three main theories given by Coulomb for studying earth pressure. The theories are: 1. Coulomb’s Wedge Theory for Earth Pressure 2. Coulomb’s Theory of Active Earth Pressure 3. Coulomb’s Theory for Passive Earth Pressure. 1. Coulomb’s Wedge Theory for Earth Pressure: Coulomb (1776) developed the wedge theory for determination […]

Rankine’s Theory of Active Earth Pressure | Soil
Article shared by :
Rankine (1857) considered the equilibrium of a soil element at any depth (h) in the backfill behind a retaining wall and determined the active earth pressure. Rankine assumed that the soil element is subjected to only two types of stresses: i. Vertical stress (σz) due to the weight of the soil above the element. ii. […]

In this article we will discuss about the design features and types of soil samplers. Design Features of Soil Samplers: The basic tool used for the collection of undisturbed soil samples from test pits or boreholes at required depth is known as a soil sampler. The fundamental requirement of a sampling tool is that when […]
