Abstract In order to protect residents in the Laugneri residential area from block slips and landslides, the municipality of Weggis has implemented a novel protective structure on steep terrain as part of its natural hazards master plan. Potential dynamic impacts are absorbed by the reinforced earth protective dam and transferred to the stable rock substrate […]
1. Background The demand for raw materials continues to grow unabated, and efforts to decouple economic performance from resource consumption have so far been largely unsuccessful. According to estimates, global raw material consumption will at least double over the next 30 years (1). The construction sector plays a very important role in terms of efficient

1. Summary The following article describes the redesign of an existing harbour promenade in the Lower Elbe area in order to increase the attractiveness of the harbour area, open up the former exclusively commercial harbour area and integrate the harbour into city life. This requires raising the ground level. Due to the low-bearing soil layers
Abstract Due to rapid advances in computing technology, it is now possible to process extremely large amounts of data in a short period of time. Accordingly, it is now feasible to use photogrammetric methods, with the aid of drones, to solve geotechnical engineering problems and open up new fields of application for practical use, or

Introduction Many dam walls at river power stations were built several decades ago and now need to be upgraded and raised due to increased flood protection requirements. Dam walls are usually raised by widening them on the air side, which in many cases requires a comparatively large amount of land and encroachment on the air-side

Two practical examples are used to explain waterproofing with plastic sealing membranes and the use of geosynthetics. The new section of the A 72 motorway south of Leipzig runs over challenging subsoil with problematic geology. The area is a landscape left behind by lignite mining in the 20th century – surrounded by partially filled former
Abstract In surface-parallel layered systems, such as surface sealing of landfills, geogrids are used to make these systems steeper. The geogrids absorb high tensile forces, which are anchored at the crest of the embankment in so-called anchor trenches. The previous design approach of EBGEO (2010) contains a number of assumptions that must be considered overly

1. Scope and principles The guideline "836.4107 Construction in water protection areas" is a continuation of the previously applicable regulation "836.0509 Water protection and soil protection". The new guideline takes into account the advancing state of the art and the further developed legal basis. Thematically, this guideline is related to guideline "836 Planning, constructing and

Dr.-Ing. S. Schwerdt, Magdeburg-Stendal University of Applied Sciences Summary When designing geosynthetic reinforcements to bridge earth failures, the required anchoring and overlap lengths must be determined in addition to the tensile force. When designing reinforcements using biaxially anisotropic reinforcements, the question arises as to how the load is transferred at the edges of the reinforcement.
Current developments 1. Introduction The DIN EN 13249 ff (12/2016) series of standards regulates the functions, function-related essential characteristics and applicable test methods for geosynthetics. The functions and applications are defined in DIN EN ISO 10318-1 (10/2018 edition) and the associated pictograms are standardised in DIN EN ISO 10318-2 (10/2018 edition). Fig. 1a: Functions according
