Abstract: – The landslides characterization based on physical parameters of
the soil from Copăceni village (Cluj county, Romania) – causes, effects and
technical measures for rehabilitation. The study area, located 25 km south
from Cluj-Napoca city and 7 km north from Turda city, in Copăceni locality, near
the Transylvania Highway, is threatened by the landslides, actives or
susceptible to be reactivate. The main factors causing the landslides are both
natural (as slope morphology, soil features or rainfalls) and anthropogenic
(overgrazing, highway construction). Field observations and measurements
together with determination of physical parameters of the soil have been
conducted in three different points, in order to describe the landslides
characteristics, to identify the causes producing the landslides, their effects
on environment and humans, and to offer solutions for rehabilitation of the
studied area. Thus, the studied landslides are considered as being superficial,
shallow and active. The sliding surface is situated at 1.60 meters deep. Small
water accumulations can be observed in the lowland areas, resulting marshes
zones, present even during the dry periods. The overgrazing is the main
identified cause producing the landslides. Due to the fact that these landslides
can affect the houses, the gardens, the agricultural areas situated in the
vicinity, the road between Copăceni and Săndulești, as well as the Transylvania
Highway, some prevention and control measures are necessary.
