The soil pressure on underground structures

Prior to production and to the construction of underground structures soil in an unlimited array is in a state of natural or geostatic equilibrium under the action of its own weight. In this case, the depth Z in the soil (Fig. 1), the following compressive stresses (pressure):

vertical

horizontal

where is the average bulk weight of overlying soils; – the coefficient of lateral earth pressure under conditions of natural occurrence.

Earth pressure on underground structures is different than the pressure in the intact rock mass at the same depth, as: Continue reading
