Re: Retaining wall design pressures

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The user's manual for retain pro states: If a portion of retained height is
below a water table, the active pressure of the saturated soil will increase
below this level. The additional pressure for the saturated soil is equal to
the pressure of the water, plus the weight of soil in water (62.4-1), plus
the (any?)surcharge of the soil above the water table.
