Foundation Engineering Chapter 8: Design and Analysis of Retaining Walls 6 8.4 FORCES ACTING ON RETAINING WALLS The design of a retaining wall must account for all applied loads. The loads that are of primary concern are the lateral earth pressures induced by the retained soil. Under norma Engineering Discoveries Retaining Wall Design Calculations Excel Suite includes all 8 of our retaining wall design spreadsheets. The design of retaining walls can be a complex undertaking, particularly when using BS EN 1997. The retaining wall must be designed to resist the sliding and overturning forces exerted by the retained material Calculations by themselves may not accurately evaluate potential failure modes which run through the retained soil, reinforced soil mass and block facing. The example problems in this manual are based on walls constructed with Allan Block Retaining Wall System's AB Stones. The AB Stones provide a nominal setback of twelve degrees from. A general rule of thumb- the back terraced wall must be set back from the front wall twice the front walls height i.e., for a 3 foot front wall, back wall must be back 6 feet. If the back wall is inside of that zone, then the wall is considered as one wall, and the 4 foot building permit and engineering is required The self-weight component of the retaining wall should be factored down or to be multiplied by weight reduction factor (0.9) to account for uncertainty because they are stabilizing in this context

Retaining wall design could include any or all of loads and forces which are explained in the following sections: 1. Lateral Earth Pressure Acting on Retaining Wall. The main purpose of retaining wall construction is to retain soil; that is why soil lateral earth pressure is a major concern in the design ENGINEERING AND DESIGN Retaining and Flood Walls ENGINEER MANUAL. retaining walls which will not be subjected to hydraulic loadings or severe Earth Force Calculation, Coulomb's Equations Earth Force Calculation, General Wedge Method Earth Pressure Calculations Including Wall Retaining Wall publications, software and technical guidance for the career development, information, and resources for Geotechnical Engineers. Information includes Retaining wall type, calculations, design examples, lateral earth pressures, overturning, sliding, surcharge pressure, pore water pressure, earthquake pressure, passive, at-rest, active, Log Spiral Theory, Coulomb method, graphical. Foundation Engineering Retaining Walls Introduction Retaining walls must be designed for lateral earth pressure. The procedures of calculating lateral earth pressure was discussed previously in Chapter7. Different types of retaining walls are used to retain soil in different places. Three main types of retaining walls: 1 1.10 Retaining wall design calculations should follow good engineering judgment and or standard design methodologies such as Allan Block, NCMA, AASHTO or FHWA. All methodologies should follow standard minimum design safety factors. Sliding: Minimum Safety Factor > 1.5; Overturning: Minimum Safety Factor > 2.0; Bearing: Safety Factor > 2.

A variety of wall types, such as poured concrete walls, concrete or masonry block walls, sheet pile walls, and others can then be designed and built to achieve the desired outcome. For taller walls, it will also be necessary to utilize a soil engineer or geologist to ensure the surcharge of the soil is retained by the proper type of retaining. Retaining wall design is an iterative process. An initial geometry is usually assigned to the wall and the appropriate forces are calculated. The actual forces are then checked using acceptable factors of safety and the geometry is revised until satisfactory factors of safety are reached. There are however, common dimensions for walls that are available that can be used as a first cut Stability Checks for Retaining Walls. Overturning and sliding checks are done to make sure the stability of retaining walls. In addition to this, base bearing pressure is also checked to confirm whether it is within the limit. In this calculation, we are concentrating on the two stability checks of sliding and overturning. Assumption Eccentricity, max and min soil pressure. Calculate the eccentricity, maximum and minimum soil pressure beneath the base of a retaining wall. Bearing pressure resultants. Calculate the bearing pressure resultants for the toe and heel of a concrete cantilever retaining wall to be used in the reinforcement calculations. Check bearing capacity

Retaining wall cost varies by material. Poured concrete is typically the most expensive, followed by wood timber and then stones and pavers. Planning a Retaining Wall. Before building a retaining wall, plan it out. Avoid placing the retaining wall where downspouts are pointed to keep standing water from forming inside the wall Tips for Installing Boulder Retaining Walls. Bigger is better. Boulder size should increase as wall height increases. Heavier walls are more resistive to erosion, freeze/thaw cycles, etc. Walls over 8 feet (sometimes even over 4′) need engineering (i.e. use Geogrid

A wall for holding in place a mass of earth or the like, as at the edge of a terrace or excavation. A retaining wall is a structure designed and constructed to resist the lateral pressure of soil, when there is a desired change in ground elevation that exceeds the angle of repose of the soil.. A basement wall is thus one kind of retaining wall Retaining walls are required for slopes and structural purposes, as they use footings to hold a wall in place and better retain soil. Although they are most common for homes built on hills or sloping properties, retaining wall blocks also provide creative design options for planter areas, elevated landscapes, and other more visual applications RETAINING WALL In the design of retaining walls or other retaining structures, it is necessary to compute the lateral earth pressure exerted bythe retaining mass of soil. The equation of finding out the lateral earth pressure against retaining wall is one of the oldest in Civil Engineering field Face of wall 5. Crib Wall Design Basic soil parameters; Unit weight of soil Angle of friction Cohesion Then the lateral pressure distribution will be known.

Alternatively, specifiers often require the wall engineering plans to be provided as part of the retaining wall construction package (design/build). In such a case, the specifier provides the retaining wall product type, location, layout, grading and soils information. Bidding contractors estimate the materials, labor and final engineering costs Retaining walls are structure used to retain soil, rock or other materials in a vertical condition. Hence they provide a lateral support to vertical slopes of soil that would otherwise collapse into a more natural shape. Most common materials used for retaining walls are The design of retaining walls requires a thorough knowledge of structural and geotechnical engineering.
