Abstract
The nice ancient Bulgarian town Balchik is situated on deep (70m) landslide on the Bulgarian Black Sea cost. The genesis of this enormous landslide is supposed in last geological periods when the Black Sea level had changed around 300m. The geologic structure is a celebrated combination of Sarmat limestone, marl and sensitive clay. The mechanics of failure reminds the landslides of Anchorage (Alyaska) from 1962 even without tsunami. Through 80-th and 90-th years of the last century the landslide has been protected by the complex of, maybe, all known means for Cost protection and the aim has attained. The complex includes general precautions (ruble groins, spur dykes, drainage gallery…), many local precautions (pre-stressed anchors, drilling drainages, buttresses, walls…), additional precautions (rehabilitation of canals, reconstruction of buildings…) etc. In the report are presented the erected protection complex, some studies results of the monitoring. The study of the landslide had started from the beginning of the last century and the monitoring and analysis of the protection is from the end of the last century.
