Hydrostatic Pressure, Ground Water behind the Structure
| Hydrostatic pressure, groundwater behind the structure |
The heel of a structure is sunk into impermeable subsoil so that the water flow below the structure is prevented. Water is found behind the back of structure only. There is no water acting on the front face. Such a case may occur when water in front of structure flow freely due to gravity or deep drainage is used. The back of structure is loaded by the hydrostatic pressure:
where: | γw | - | unit weight of water |
hw | - | water tables difference |
