Example No$\mathrm{.}4$: $,$ Sheet pile wall design $-$ wall with tieback anchor

Design anchored sheet pile wall for foundation pit of depth $h_1=2**h$ acc. to Ex$.$ No$.3.$ Anchor level $a=0,2**h_1$ applying "Blum's" method of calculation $-$ with free toe rotation. Site conditions are similar to those in Ex$.$ No$.3.$ Ground water is $5$ m below foundation level. Design the wall toe depth, calculate load, tangential force, bending moment and draw distribution diagrams. Anchor design: length and root dimensions, provide stability assessment of the supporting system.
