Loads can be categorized into dead loads, live loads, surcharges, and lateral earth pressure and these must always be considered in the design of a retaining wall. Although it's not common, wind loads might also play a role, for example, if there is a large exposed area on the top of the wall due to the installation of billboards. Thorough site analysis is crucial to understanding the soil properties, water tables, and slope stability.
About SkyCiv

A mortared wall needs a footing and a drainage system that will defeat frost heaving. A dry, nonmortared wall allows water to seep through, relieving pressure behind the wall naturally. The depth you need to excavate depends on frost depth as well as the wall and soil type.
What is the design process for designing a structural retaining wall?
With the full retaining wall design software, a PDF design report can be generated to show the detailed calculations steps and references followed to achieve the results. Thickness of a retaining wall depends entirely on the planned purpose and location of your retaining wall. The idea is to create a wall with sufficient wall thickness to tolerate the allowable soil bearing pressure behind it, without the retaining wall design being too thick, which wastes money and time.

If you are looking to use SkyCiv to model a concrete retaining walls, this is the best place to start!
ASCE 7, "Minimum Design Loads for Buildings and Other Structures," provides provisions for calculating loads on structures, including retaining walls. ASCE 7-16 is the latest version and is widely adopted in the industry. Replace native soil with 3/4-minus gravel (no stones under 3/4 inch in diameter) or “bank-run” gravel (washed stones 1/4 inch to 6 inches in diameter). Shovel at least a 4-inch layer of gravel onto the landscape fabric.
Stone-Crete is used for sound barrier walls, retaining walls, subdivision entry walls or wherever a beautiful deep relief stone wall is desired. Stone-Crete's mass production techniques minimize costly masonry work while providing the structural and aesthetic quality of concrete. Please note that this is a simplified example to demonstrate the steps involved in retaining wall design. In practice, a detailed analysis, considering various factors such as soil properties, groundwater conditions, and local regulations, is required for a comprehensive and accurate design.
Materials
A retaining wall is a structure that is designed to hold soil behind it. Retaining walls are frequently used to transform uneven or hilly ground and create more flat, usable land. This also helps to protect your landscaping from soil erosion and ground collapse. A common application is a retaining wall planter, which surrounds the perimeter of a house or fence and creates a raised, protected environment for your plants.

The properties of the retained soil, including its cohesion, angle of internal friction, and potential for settlement, must be assessed to determine appropriate design parameters. Additionally, knowledge of the water table is essential to assess hydrostatic pressure and potential drainage requirements. To ensure the effectiveness of a retaining wall, several basic principles should be considered. Proper drainage is essential to prevent water buildup behind the wall, which can increase hydrostatic pressure and compromise stability. Adequate load distribution across the wall and consideration of the retained soil's properties are also vital for maintaining structural integrity.
Lateral Earth Pressure
Install the soil nails at the specified spacing and length, ensuring proper bonding with the surrounding soil. Enhance your workflows with access to the world's most trusted engineering codes and standards. For the thickness of the wall to be safe in shear, the ultimate shear, Vu should less than the allowable shear, Vallow as recommended by the ACI 318 code.
But unless you own or rent one and know how to use it properly, just use a 4-ft. The tamper, brick tong and block chisel are available at rental yards. This wall, created by Ron Odell's Custom Concrete, is over one hundred feet in length, more than a foot wide and took three truckloads of concrete to pour. To achieve the layered look light gray concrete was poured in the bottom of the forms and then sprinkled with rocks and other natural debris which was followed with dark gray concrete. Retaining walls provide lateral support to vertical slopes of soil. They retain soil which would otherwise collapse into a more natural shape.
Mortared or concrete walls in heavy-frost areas require footings dug below the frost line. Nonmortared walls should be built on a gravel-filled trench dug below frost line. If you live where it doesn’t freeze and your soil drains well, you may be able to just scrape away topsoil to form a base for nonmortared walls. Weepholes actually penetrate the retaining wall and drain the area immediately behind the wall.
