![]() | Modern Earth Structures for Transport Engineering: Engineering and Sustainability Aspects Subjects: Earth Sciences; Engineering & Technology; Transport & Vehicle Engineering; Earth Sciences; Civil Environmental and Geotechnical Engineering; Geology - Earth Sciences; Soil Science; Transportation Engineering; Nowadays, demands on modern civil engineering structures require not only safe technical solutions, but also additional approaches, involving ecological, sociological and economical aspects. This book reacts on these new requirements with a focus on earth structures for transport engineering, mainly for motorways and railways. Technical demands have to be adequately related to the risk with which the design and execution are connected. Soil used for the construction, together with subsoil, are natural materials with a high degree of inhomogeneity. Therefore, the risk when constructing with such materials is much higher than for structures utilizing man-made materials. The engineering approach is firstly focused on the geotechnical risk identification and subsequently on the reduction of this risk. Geotechnical risk is linked to the uncertainties for individual phases of the design and construction processes. Ground model, geotechnical design model, calculation model and structure execution are the main phases of the above-mentioned processes. Risk reduction involves the lowering of the range of uncertainties for individual phases, guaranteeing safe and optimal technical solutions. Eurocode 7 "Geotechnical design" creates a general frame of this risk identification and reduction approach. Earth structures are offering great opportunities for sustainability approach. Therefore, the possibilities how to decrease consumption of land (greenfields), energy and natural aggregates are at the centre of interest. In parallel to sustainability, the principles of availability and affordability for transport infrastructures are discussed. The main aim there is to eliminate the impact of interaction of the transport infrastructure with natural and man-made hazards, thus guaranteeing long-term functionality. Ivan Vaníček is Professor in Soil Mechanics and Foundation Engineering at the Czech Technical University in Prague. His research interests are tensile soil characteristics, tensile cracks, application of geosynthetics and environmental geotechnics, all with focus on the design and behaviour of earth structures. Consulting activities: about 500 cases local and abroad. He is chairman of the Czech Geotechnical Society, organizer of 13th European conference on Soil Mechanics and Geotechnical Engineering in Prague 2003, past vice-president of ISSMGE for Europe (2009-2013). Member of the ELGIP platform. He presented invited lectures in more than 40 countries. He is author and co-author of many textbooks, and monographies such as "Earth structures in Transport, Water and Environmental Engineering"; Sustainable construction, Micro-measuring and monitoring system for ageing underground infrastructures. Activities in CEN250/SC7, namely WG 1 - preparation of the second generation of EC 7 Geotechnical design. |
