Stages of geotextile container deformation during the opening of the split barge. Where
b
0
=
opening width of the split barge [m] and
b
free
=
the opening width at which the container
starts to slide to the opening [m].
L
=
length of the geotextile container [m];
ϕ
=
angle of shearing resistance between the floor of the split barge and the
geotextile [deg];
θ
=
angle of the split barge floor to the horizontal [deg].
When there are many folds at the bottom of the geotextile, it is possible that the
geotextile container immediately enters stages II or III, and bypasses stage I.
STAGE II
Stage II begins when the whole geotextile container begins to shift along the sides of the
split barge towards its opening. Little deformation of the geotextile container occurs
