Chapter 12: Lateral Earth Pressure
Civil Engineering Department: Foundation Engineering (ECIV 4052) Engr. Yasser M. Almadhoun Page 1 Part 4: Lateral Earth Pressure and Earth -Retaining Structures Chapter 12: Lateral Earth Pressure Introduction Vertical or near-vertical slopes of soil are supported by retaining walls, cantilever sheetpile walls, sheet-pile bulkheads, braced cuts, and other, similar structures. The proper design of those structures requires an estimation of Lateral Earth Pressure , which is a function of several factors, such as: (a) the type and amount of wall movement, (b) the shear strength parameters of the soil, (c) the unit weight of the soil, and (d) the drainage conditions in the backfill.
Coulomb’s Active Earth Pressure To apply Coulomb’s active earth pressure theory, let us consider a retaining wall with its back face inclined at an angle with the horizontal, as shown in Figure 12.12a. The backfill is a granular soil that slopes at an angle α ... For Mohr’s circle, the major principal stress is σ’ ...
