The mechanism of consolidation was explained by Terzaghi with the help of a spring-dashpot model using soil-spring analogy. 1. Spring-Dashpot Model: Figure 11.1 shows a dashpot consisting of a cylinder containing a spring supporting a piston. The cylinder is completely filled with water and has an outlet valve to regulate the outflow. Let the initial stress in the spring be [...]
In this article we will discuss about:- 1. Introduction to Terzaghi’s Theory of Consilidation 2. Assumptions in Terzaghi's Theory of Consolidation 3. Validity of Terzaghi's Theory 4. Solution of Consolidation Equation. Introduction to Terzaghi’s Theory of Consilidation: The total consolidation settlement is time dependent. It is often necessary to determine – i. Settlement that occurs in a given time after [...]
Consolidation test consists of applying the pressure on a thin soil specimen in increments and keeping each pressure increment for sufficient time until the consolidation of the soil specimen and measurement of the vertical deformation of the soil specimen due to expulsion of pore water. All consolidation parameters including av, mv, Cc, cv etc. can be determined from the consolidation [...]
