Overturning (GEO),
Γ
=
2.69, 2.94
Sliding (GEO) DA1-1,
Γ
=
1.62;
DA1-2,
Γ
=
1.42
Exercise 8.2: Overturning (GEO),
Γ
=
3.26, 3.35
Sliding (GEO) DA1-1,
Γ
=
2.76;
DA1-2,
Γ
=
2.27

The depth of the excavation is to be 4 m. Determine the minimum depth of embed-
ment, d, to provide stability in accordance with EN1997-1:2004 Design Approach 1.
If the wall is now to be designed to carry a surcharge of 20 kPa, what would be
the required depth of embedment?
Answer
Surcharge
=
0: DA1-1, d
0
=
4.0 m, d
=
4.5 m;
DA1-2, d
0
=
5.4 m, d
=
6.0 m
Surcharge
=
20 kPa: DA1-1, d
0
=
5.0 m, d
=
5.6 m;
DA1-2, d
0
=
6.9 m, d
=
7.7 m
