DIN 19702:2010-06

German standards have an internationally high reputation in the field of "large-scale" water engineering. Their exceptionally long time of application underlines their character acknowledged by the international scientific community as accepted regulations of technology. In recent years a number of important measures have been realized with German know-how in hydraulic engineering in various countries. Planning, design, construction management and construction work supervision are probably the most important fields of activity, when dealing with solid structures in hydraulic engineering. Due to their extraordinary significance, amongst others for water supply, measures of flood protection, expansion and design of shipping routes, integration into existing landscape structures, but also due to their inherent potential threads, engineers who have the required suitability and technical qualification shall be authorized to carry out these activities. This standard specifies the basic requirements for the steadiness (bearing capacity, serviceability and durability) in accordance with DIN 1055-100 for solid structures in hydraulic engineering. According to a basic standard on water engineering, this standard shall apply to any solid hydraulic structures made from plain and reinforced concrete and masonry structures in inland and coastal areas, for instance to weir systems, sluices, hydropower stations, pumping stations, intake structures, bottom structures, culvert works, solid components of canal bridges, solid flood protection structures, including auxiliary structures. Offshore structures and excavation support systems are excluded from the considerations. Standard DIN 19702:1992-10 has been completely revised due to internationally and nationally developed principles and terms in the basic standards for civil engineering and water and waste water engineering, especially for the partial safety concept. The bases of structural design, particularly the actions, and the information on stability analysis have been exactly adapted to the new concept. Loads have been subdivided into permanent, variable and exceptional loads; with regard to hydraulic engineering they have been assigned to the permanent, variable and exceptional design situations. For the design of solid structures in hydraulic engineering, loads, which are specific for hydraulic engineering, have been assigned partial safety factors. Interfaces to geotechnical proof have been indicated. The importance of durability aspects has been taken into account. The contents have been shortened, especially those contents, which have already been taken into account in the generally accepted regulations of technology, recommendations from trade associations and technical literature. New knowledge and many years of experience have been taken into account in the details on design, construction work, construction work supervision, commissioning and supervision of structures. The standard has been prepared by Working Committee NA 119-02-05 AA "Standsicherheit von Wasserbauten" ("Stability of structures in water engineering"). With respect to DIN 19702:1992-10 the following changes have been made: a) the title has been changed in order to make a clear reference to the aspects mentioned in the standard; b) a complete revision of the standard - by taking into account internationally and nationally developed principles and terms in the basic standards for civil engineering and water and waste water engineering; - by shortening the contents, which have already been taken into account in the generally accepted regulations of technology, recommendations from trade associations and technical literature; - by taking into account new knowledge and many years of experience in the details on design, construction work, construction work supervision, commissioning and supervision of structures; c) editorial revision.
