Increased Active Pressure
The increased active pressure is calculated using k coefficient.
The magnitude of the pressure is calculated by the formula:
where: | σr | - | pressure at rest |
σa | - | active earth pressure | |
k | - | coefficient of increased active pressure |
If the value of coefficient k=1, then the acting pressure is equal to the pressure at rest. If the value of coefficient k=0, then the acting pressure is equal to the active pressure.
