state, a settlement calculation shall be used;
- an indirect method using comparable experience and the results of field
or laboratory measurements or observations, and chosen in relation
to serviceability limit state loads so as to satisfy the requirements of all
relevant limit states;
- a prescriptive method in which a presumed bearing resistance is used
(see 2.5).
6. Calculation models for ultimate and serviceability limit state design of spread
foundations on soil given in 6.5 and 6.6 respectively should be applied.
Presumed bearing pressures for the design of spread foundations on rock
should be applied according to 6.7.
6.5 Ultimate limit state design
6.5.1 Overall stability
1. Overall stability, with or without the foundations, shall be checked particularly
in the following situations:
- near or on a natural or man-made slope;
- near an excavation or a retaining wall;
- near a river, a canal, a lake, a reservoir or the sea shore;
- near mine workings or buried structures.
2. For such situations, it shall be demonstrated using the principles described in
Section 11, that a stability failure of the ground mass containing the
foundation is sufficiently improbable.
6.5.2 Bearing resistance
6.5.2.1 General
1. The following inequality shall be satisfied for all ultimate limit states:
V d
= R d
[6.1]
2.R d
shall be calculated according to 2.4.
3. V d
shall include the weight of the foundation, the weight of any backfill
