BS-Theory: Passive earth pressure -Aufzählung
The coefficient of passive earth pressure can be calculated using several methods:
DIN 4085:2017,
DIN 4085: 2017 planar slip surfaces,
Streck,
Caquot/Kerisel,
DIN 4085:2017 planar slip surfaces/Caquot/Kerisel,
Culmann.
The earth pressure after Culmann is acquired by varying the slip surface angle (see Piling Handbook 1977). The forces at the earth pressure wedge are calculated using a slice method.
