Upload NowThe depth of a well foundation is decided based on the following three considerations: 1. Maximum scour depth below the highest flood level (HFL). 2. Minimum grip length below the scour level. 3. Allowable bearing capacity. The depth of a well foundation is thus equal to the sum of the maximum scour depth and the […]

How to Prevent Tilting and Shifting of Wells? | Soil Engineering
Article shared by :
Sinking 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 […]
