9.1 Introduction Methods of analyzing sheet-pile walls: 冬 Classical (original)methods:The free-earth support and Fixed-earth support Assumption:active (from filled side)and passive pressure on the free side below the dredge line. The design was based primarily on taking moments about the anchor rod,increasing the depth of embedment D until >F was satisfied, and then computing the resulting bending moments in the piling. 9.1 Introduction ❖ Methods of analyzing sheet-pile walls: ❖ Classical (original) methods: The free-earth support and Fixed-earth support ❖ Assumption: active (from filled side) and passive pressure on the free side below the dredge line. ❖ The design was based primarily on taking moments about the anchor rod, increasing the depth of embedment D until ∑Fh was satisfied, and then computing the resulting bending moments in the piling
