Slope stability refers to the condition of inclined soil or rock slopes to withstand or undergo movement; the opposite condition is called slope instability or slope failure. The stability condition of slopes is a subject of study and research in soil mechanics , geotechnical engineering , and engineering geology .
The main objectives of slope stability analysis are finding endangered areas, investigation of potential failure mechanisms, determination of the slope sensitivity to different triggering mechanisms, designing of optimal slopes with regard to safety, reliability and economics, and designing possible remedial measures, e.g. barriers and ...
Slope mass rating (SMR) is a rock mass classification scheme developed by Manuel Romana [1] [2] [3] to describe the strength of an individual rock outcrop or slope. The system is founded upon the more widely used RMR scheme, [4] which is modified with quantitative guidelines to the rate the influence of adverse joint orientations (e.g. joints dipping steeply out of the slope).
Steel wire mesh may be used for soil and rock slope stabilization. After leveling, the surface is covered by a steel-wire mesh, which is fastened to the slope and tensioned. It is a cost-effective approach. Wicker or brushwood mats made of vegetable material. Very long and flexible willow branches can be used, which are then covered with infill ...
The method is an extension of the Newmark's direct integration method originally proposed by Nathan M. Newmark in 1943. It was applied to the sliding block problem in a lecture delivered by him in 1965 in the British Geotechnical Association's 5th Rankine Lecture in London and published later in the Association's scientific journal Geotechnique.

The selection of hillslope stabilization treatments should consider three key elements: (i) the effectiveness of the treatment, (iii) the cost of production and transport, and (i) the values-at-risk to be protected [3] The most cost-effective treatment might not be adequate to protect critical values-at-risk whereas the treatment with the highest effectiveness and cost could not be suitable to ...
Cross section of a slope with soil nails installed. Soil nailing is a remedial construction measure to treat unstable natural soil slopes or unstable man-made (fill) slopes as a construction technique that allows the safe over-steepening of new or existing soil slopes.
Soil stabilization is a general term for any physical, chemical, mechanical, biological, or combined method of changing a natural soil to meet an engineering purpose. [1] Improvements include increasing the weight-bearing capabilities, tensile strength, and overall performance of unstable subsoils , sands, and waste materials in order to ...
