Upload NowSinking of wells usually encounters difficulties in the form of tilting and shifting of wells. Tilting is the deviation of the vertical alignment of the well and shifting is the deviation from the horizontal alignment. Tilting and shifting are associative; shifting occurs if tilting is large and uncontrolled. Shifting can be eliminated, if the well […]

Rankine’s Theory of Passive Earth Pressure | Soil
Article shared by :
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 […]
Poncelet’s Construction for Earth Pressure | Soil Engineering
Article shared by :
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 […]
