Slope Stability Investigation

Post 17121 of 23787

Slope stability is the potential of soil covered slopes to withstand and undergo movement. Movement can be slow and gradual known as creep or rapid resulting in catastrophic slip or collapse.

Stability is determined by the balance of disturbing factors such as soil load and additional; or surcharge loadings in opposition to the resisting strength of the ground.

A previously stable slope may be initially affected by preparatory factors, making the slope conditionally unstable. Triggering factors of a slope failure can be climatic events such as heavy rainfall causing the slope to become actively unstable, leading to mass movements. Mass movements can be caused by increase in shear stress, such as loading (eg. placement of a spoil heap or weight on the slope) lateral pressure (eg. water pressure in the rockmass behind the slope or a burst water pipe) and transient forces such as earth quakes tremors. Alternatively, the strength of the ground may be decreased by weathering, changes in pore water pressure, and organic material.

At Geoinvestigate Slope Stability Investigation, analysis (including computer modelling), and design mitigation is typically completed by our professional geologists, Engineering Geologists, and Geotechnical Engineers.  Our geologists and Engineering Geologists can also use their knowledge of earth process and their ability to interpret surface geomorphology to determine relative slope stability based simply on site observations.
