Equilibrium stress field for a foundation.
Figure 19.14 shows mechanisms and displacement diagrams for slip fans: Fig. 19.14(a)
is for undrained loading and Fig. 19.14(b) is for drained loading. You shouldwork your
way through these using the description of the construction of displacement diagrams
given in Sec. 2.4. From the geometry of Fig. 19.14(a),
