Design situations and limit states

ยง9 of Eurocode 7 Part 1 includes a series of illustrations showing limit modes for gravity walls, including overall stability, foundation failure, and structural failure. Figure 11.2 gives examples of ultimate limit states that can affect mass gravity walls. From left to right, these include: toppling, sliding, and bearing failure.

fi.e. weaker strata are unlikely to occur at depth, structural weaknesses such as faults are absent, and solution features and other voids are not expected.

Examples of ultimate limit states that can affect L- and T-shaped gravity walls are shown in Figure 11.3. From left to right, these include: (top) toppling, sliding, and bearing failure; and (bottom) structural failure of the wall's stem and toe.
