Lagging
The lagging is considered as the simply supported beam. The beam length l is the same as the spacing of soldier piles.
The maximum values of internal forces (bending moment and shear force) are calculated according to the selected type of load:
- Rectangle:
Beam static scheme - Rectangle
- Triangle:
Beam static scheme - Triangle
Where: | qmax | - | maximum pressure (to the excavation level) |
h | - | cross-section height | |
l | - | soldier piles spacing |
