Caltrans retaining wall manual

ADMINISTRATIVE MANUAL S COUNTY OF LOS ANGELES. DEPARTMENT OF PUBLIC WORKS. GEOTECHNICAL AND MATERIALS ENGINEERING DIVISION. SEISMIC EARTH PRESSURES ON RETAINING WALLS. The following provides clarification on the County’s policy regarding the calculation of seismic earth pressures on retaining walls. Engineering Instruction EI revises Section Fill Type Retaining Walls by combining (1) two Standard Specification Sections which contain proprietary fill type retaining walls (Section Internally Stabilized Fill Structures and Section Precast Modular Walls) and (2) a special specification into one, comprehensive Standard Specification. B Salvaged Material Retaining Wall (Value Engineering)! Identify and qualify source(s) of salvaged material! List of desired salvaged materials at each source! Complete design and specifications for salvaged material retaining wall (or use one of the existing design), including: ♦ Wall type ♦ Wall batter ♦ Reinforcement type and layout.
