Abstract

Abstract: The paper is focused on principle of sustainable development with respect to the earth structures of transport engineering and different possibilities and examples are described in more details. Situation of new motorways, railways, airport, parking areas is preferred on land, which is low value for agricultural purposes. Such land is for example brownfields, marshlands, old mining areas or areas prone to landslide and to find technical solution for such problem is a great challenge for us. From the cross section point of view as well as savings of land, the comparison is made between reinforced and unreinforced slopes, together with demands for steeper slopes of fill and cut. The utilization of different large volume waste materials, construction and demolition wastes, and excess of excavated soil in cities, is described not only from the view of mechanical, physical properties specification but also from the environmental view, solving the character and spreading of leachate. The application of sustainability approach is possible with the help of smart geotechnical structures, which are presented and compared with classical solution. These smart geotechnical structures are fulfilling conception of sustainable development not only from the short-term view, but predominantly from the long term functionality, taking into account also demands for maintenance and structural ageing. The significance of the quick and realistic evaluation of the alternative structures from the view of price, energy, natural materials and land consumption, production of C02 will be stressed at this level. Finally, the resistibility of these structures to the risk of failure associated with either design phase as phase of long-term functionality is discussed from the view of structure robustness. To be able to guarantee the functionality even under unexpected situations, e.g. natural hazards.
