Slope Stability and Excavation Stability Assessment / Risk Assessment

This assessment is carried out by our geotechnical engineers in accordance with Australian Geomechanics Society (2007c) 'Practice Note Guidelines for Landslide Risk Management, Australian Geomechanics, Vol 42, No 1, March  2007 and NSW WorkCover Excavation Work Code of Practice 2015.

 

We can provide professional advise on existing ground stability, excavation stability, battering and benching methods and suitable retaining walls.

​

Slope and excavation stability analyses are used in a wide variety of geotechnical engineering problems, including, but not limited to, the following:

​

• Determination of stable cut and fill slopes;

​

• Assessment of overall stability of retaining walls, including global and local stability (includes permanent systems and temporary shoring systems);

​

• Assessment of overall stability of shallow and deep foundations for structures located on sloping grounds over potentially unstable soils, including the determination of lateral forces applied to foundations and walls due to potentially unstable slopes;

​

• Stability assessment of landslides (mechanisms of failure, and

determination of design properties through back-analysis), and design of mitigation techniques to improve stability;

​

• Evaluation of instability due to liquefaction.

​

We can also analyse the stability of slopes and excavations using computer software (finite element modelling/numerical analysis).
