Upload NowThe 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 […]

How to Conduct Consolidation Test of Soil? | Soil Engineering
Article shared by :
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 […]

In this article we will discuss about:- 1. Need for Using Sand Drains 2. Advantages of Sand Drains 3. Construction. Need for Using Sand Drains: Structures constructed over highly compressible soils, soft marine clay deposits suffer very large consolidation settlements, which have the potential to cause serious damage or failure of such structures. Such soils, […]
