Rockfall embankments. Innovative design and construction methods

The Austrian standard ONR 24810, 2020 regulates the effects of actions, design, construction, monitoring and maintenance of rockfall protection embankments. This standard describes the design concept and the constructions in detail. The basic principles are based on the research results of Hofmann & Mölk, 2012, Hofmann et al., 2013, Hofmann et al., 2017 and Hofmann et al., 2020. The constructions are differentiated into five types depending on the front facing and the geosynthetic reinforcement (Table 2). Type I refers to embankments without geosynthetics.
Embankments with a stone facing on the uphill side are type II. The constructions reinforced with geosynthetics represent the construction types III, IVa and IV b. The geosynthetic-reinforced embankments without increased transverse distribution of the impact loads is type III, the geosynthetic-reinforced embankments with increased transverse distribution is type IVa and with strongly increased transverse distribution is type IVb. This design concept is used e.g. in Austria, Switzerland, Germany, Italy and Norway.

CiteScore:
2020: 3.8
CiteScore measures the average citations received per peer-reviewed document published in this title.
CiteScore values are based on citation counts in a range of four years (e.g. 2016-2019) to peer-reviewed documents (articles, reviews, conference papers, data papers and book chapters) published in the same four calendar years, divided by the number of these documents in these same four years (e.g. 2016 —19).
Source Normalized Impact per Paper (SNIP):
2019: 1.307
SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SCImago Journal Rank (SJR)
2019: o.657
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal's impact.
Journal Metrics: CiteScore: 1.0 , Source Normalized Impact per Paper (SNIP): 0.381 SCImago Journal Rank (SJR): 0.163
