Hydraulic structures using scrap tires for bank protection include tire mats, revetment (retaining walls, seawalls, revet mattresses), and tire-concrete imits. In search for economical bank-protection structures, the use of scarp tires as a less-expensive alternative is desirable, considering the costs of the metal and concrete used in reinforced-concrete construction, especially in developing countries. Whole scrap tires can be utilized for surface erosion control, beach and slope protection, and stream bank stabilization. In these applications, scrap tires are banded together and partially or completely buried on imstable slopes. Tires can be used with other stabilization materials to reinforce an unstable highway shoulder or protect a channel slope remained stable and can provide economical and immediate solutions. In bank protection structures, tires are laced together by steel cables and used as a protective layer or mat over stream banks or soil embankments. The top, toe, upstream and downstream ends of the mattress are tied into the banks. Used tires with metal cords were shown to bean excellent construction material that can partially replace reinforced concrete for protection of river banks and canal walls [19]. 

Slope reinforcement is also employed in the construction of embankments, and as an alternative to some retaining walls. To provide slope stability, multiple layers of geogrids, or woven/knitted geotextiles, may be placed during construction in the fill material used to make the slope. 

In some cases. Projects 2 and 3 are merged, where the stability of a slope whieh ineludes the analysed retaining wall is done as part of verifying its external stability. 

Geotechnical topics covered during the first cycle include soil formation, phase relationships, soil classification, principle of effective stress, seepage, consolidation, shear strength, drained and undrained conditions, essentials of Eurocode 7, retaining walls, shallow foundations, slope stability, and field investigations. There are three class hours of lectures and two class hours of exercises per week, within a semester consisting of 15 weeks. With this list of topics, basic soil mechanics principles escape students, who attend... 

If the site involves a slope, or if the site is a railroad embankment, an earthquake might cause the slope to collapse. In this case the angle of repose of the slope could be reduced. If that is not possible, a retaining wall may be required, or a geotextile (made from polyester or polypropylene) covered with sand could be used to stabilize the slope. 

Slope-stabilization techniques are commonly used in road cuts to prevent rock fall and landslides. These techniques include structural solutions (such as gabions, retaining walls, and spray-on concrete) and less structural approaches incorporating geotextiles and revegetation. 

Additional stability calculations for global stability must always be carried out, as is the case for any retaining wall structure, to ensure that the structure is not part of a larger failure mechanism that extends beyond the reinforced soil zone and into the foundation. These calculations can be carried out using conventional slope stability programs.
