Earth pressures on retaining structures

To design the earth supporting structures, such as sheet pile walls, knowledge of the soil properties is needed to assess the resulting soil pressure on the retaining structure.

OGI provides the expertise to collect the data from site investigation and to provide alternative designs.

A range of methods, including finite element method, is available to assess the soil-structure interaction, surcharge loads and other factors needed to provide an optimum retaining wall design.

Earth slope design

Unsupported slopes often outperform other methods of providing space for the construction of foundations and other deep structures.   

Careful site investigation and design need to be carried out in order to mitigate all associated risks and fulfil the legal requirements.  

The OGI team is well equipped with a portfolio of calculation methods to asses slope stability, and is prepared to deal with non-standard conditions for slope design.

The ability to react to changing operational situations on site and to changing geological conditions provides the client with a design that is safe at all stages of a complex and extensive excavation process.

As slope stability is closely related to pore water pressure in the soil, OGI’s clients benefit from an integrated approach having the dewatering and slope designed and optimized together.
