Geologie

  • Pe intreg tronsonul apar în aflorimente micașisturi și paragnaise apartinând Seriei de Cozia (Ante-proterozoic superior) și local pachete de gresii, acoperite la partea superioară de depozite deluviale (prafuri, nisipuri prăfoase cu pietrișuri și blocuri);
  • Versantul (în cea mai mare parte împâdurit) prezintă înclinări de până la 60 - 87° și este puternic tectonizat (frământări, cutări, microfisuri) și procese continue de dezagregare.
  • Înclinarea pachetelor de roci variază între 30 - 55° (mai mică pentru gresii și mai mare pentru micașisturi).

Situația inițială

National road no. 7 (DN7) is one of the most important routes through the Carpathian Mountains, with heavy traffic. The Olt River runs parallel to the DN7 with high mountains, directly next to the road. In winter and spring rockfalls occur regularly. Also with unstable slopes, torrents and avalanches the risk of accidents was high. 

This project was originally developed with five concrete canopies for rockfall protection. Due to costs and other restrictions, a modern solution using high tensile steel wire was chosen. After further investigation, 23 dangerous areas were found and had to be protected using two types of protection systems: active and passive.
