In the passive case, the retaining wall moves toward the soil, causing compression of the soil and increasing the lateral earth pressure. When the soil reaches the state of plastic equilibrium, the Mohr's circle touches the Coulomb's failure envelope. Thus, in the passive case, the vertical stress is more than the horizontal stress, since both the stresses are considered as [...]
In this article we will discuss how by using Poncelet’s graphical solutions we can determine active and passive earth pressure. Poncelet (or Rebhan's) Construction for Active Earth Pressure: Poncelet and Rebhan have independently given graphical solutions for determination of active earth pressure. The procedure for determination of active earth pressure in Rebhan's or Poncelet graphical method (refer Fig. 15.44) is [...]
In this article we will discuss about:- 1. Introduction to Well Foundations 2. Caissons and Its Types 3. Shapes 4. Components. Introduction to Well Foundations: Well foundations are one of the types of deep foundations that provide a solid and massive foundation typically for bridges and heavy structures. Well foundations are also useful for transmission line towers, where uplift loads [...]
