Example 11 - CAST IN Place Concrete Cantilever Retaining WALL==================================== ======================================== =========1 GENERAL INFORMATIONS tarting Element Size Assumptions:Total Footing Width = 70% to 75% of the design heightFooting Thickness = 10% of the design heightToe Width = 10% of design heightMATERIAL PROPERTIESSoil: CDOT Class 1 Backfill-Drained Footing bears on soilSoil unit weight s =kcfAngle of internal friction (backfill) = degWall-backfill friction angle = 2/3 =degCoefficient of active earth pressureKa =(Coulomb)AASHTO Eq.
EXAMPLE 11 - CAST-IN-PLACE CONCRETE CANTILEVER RETAINING WALL 13.33 Example 11 demonstrates design procedures for cast-in-place cantilever retaining walls supported on spread footing in conformance with AASHTO and Section 11.5 of this BDM. Horizontal earth pressure is applied based on the Coulomb earth pressure theory.
