Selection of the variant of highway based on the territory susceptibility to landslides – model area D1/R3 highway nearby Oravský Podzámok

Slovakia. The chosen section of the planned lineside construction is
the future section of the R3 expressway starting at the D1/R3
highway intersection in Hubová up to Oravský Podzámok. The
selected road section was investigated based on the built-up model
of the territory's susceptibility to landslides. Multivariate statistical
analysis was used to determine the susceptibility of the territory to
landslides, the success of which was determined based on ROC
curves. Four variants were compared, of which two surface and two
tunnel variants with the Dolný Kubín tunnel. By comparing the
routes of the individual variants that pass through the landslide area,
the order of suitability of the highway variants was determined in
terms of slope stability. Determining the conflict of interests of line
constructions with sites of susceptibility to landslides is very
important in the environmental impact assessment process.
Prediction of probable negative impacts of construction is one of the
basic missions of this process. Missing data, whose acquisition
extends the processing time for the project and the funding of
associated expenditures, is a common drawback when building
prediction models in the field of road construction.
