Human caused slope instabilities restoration works and a country road III/42117 putting into

part 2/2

Heavy rains in September 2014 have caused origin of shallow landslides affecting a country road

(3rd

class.) between a Pavlov.

investigation and the slope stability evaluation (03/2018). We completed 3 phases (09/2017-

04/2018) of geological and geotechnical investigations focussed on CPT tests and direct shear soil

test. New geological model and newly generated geotechnical model helped to understand natural

processes of slope instability process of origin along the country road. Evaluated global slope

stability is satisfactory with a factor of safety higher than 1.3. The main problems are wrong

excavation works taken under the slopes. This works has worsen local slope stabilities. A

restoration works design was our job for the South Moravia Authority.
