Abstract

The breakwater of the bigger Bulgarian Black See Port has erected in the first years of the XX-th century near Varna. Soon after the complained of its construction considerable settlements have appeared. Some times during the one hundred years superstructures and gravity increasing on the soil around the breakwater have made. The last restoration has made around 30 years ago and after that – 10 years later too when concrete tetrapodes have laid before the structure. Thereafter the settlements are continuing. The investigations and studies point out local no stability soil. It is delay to apply a send bed, known from the classical examples La Spetzia (Italy) and Kobe (Japan). Now a new restoration and protection is executing. Many small caissons in chess order on the See bottom before the structure have to increase the grave and the weight, to break the waves like underwater breakwater, to decrease the bottom velocities and totally to protect the stability and to stop the settlements. Schemas, profiles, history of the construction, decisions are shown in the report.

One Hundred Years Settlement of the Verna’s Breakwater - Construction on Soft Clay Like a Typical Example from University Program of Port Construction in Bulgaria

Arlington, Virginia

The breakwater of the bigger Bulgarian Black See Port has erected in the first years of the XX-th century near Varna. Soon after the complained of its construction considerable settlements have appeared. Some times during the one hundred years superstructures and gravity increasing on the soil around the breakwater have made. The last restoration has made around 30 years ago and after that – 10 years later too when concrete tetrapodes have laid before the structure. Thereafter the settlements are continuing.
