Retaining wall design is complex and must take numerous factors into consideration. The geotechnical engineering professionals at Consulting Services Incorporated (CSI), have people who are equipped to provide sound engineering solutions for both retaining wall design and retaining wall inspection.
There are a number of elements that go into the design of a retaining wall:
Safety with regard to the prospect of the wall overturning
Required wall height
Timely and cost-effective construction
Generally speaking, a retention wall serves to hold back vertical soil that would, minus the retention wall, slide, collapse or slump to its natural slope. Binding two levels of soil elevation often occurs when the terrain slope will not work for the purpose of a project, particularly when structures such as a road overpass will be constructed.
It is critical that the nature of this work must be done professionally. Most states mandate through building codes that retention walls which are over about 4 feet tall be designed by a professional engineer. Clients of CSI have the benefit of working with an engineering firm with great experience, an average of over 15 years in the field. The expertise throughout CSI provides clients with confidence that the retaining wall design will be sound.
Gravity will continue to move the retained material down slope, requiring retaining wall design to calculate lateral earth pressure on the wall from its top to its lowest depth. If not addressed correctly, the wall can push forward and/or collapse.
Groundwater is another element that must be considered in retaining wall design. If groundwater is not dissipated by a drainage system, this will increase pressure on the retaining wall. Consulting Services Inc. will do site review to determine whether or not a drainage system needs to be designed. This can be done in a number of ways and the professional consultation with CSI will determine what works best for the client's project.
General retaining wall design steps include:
Wall alignment, geometry, function, aesthetics and budget parameters
Geotechnical investigation of subsurface with appropriate testing
Wall load and side analysis
Design directed by AASHTO Load and Resistance Factor Design requirements
Checks for external stability and movement
Perform internal stability checks for wall components
