The paper contains the work of various variants
of retaining structures of engineering protection. The paper contains the
project "Engineering landslide protection of the northern slope of the
Psekhako ridge". The construction site is located in the Adler district of
Sochi. The construction area includes the Lower station of the cableway
"F" and the retaining Wall-3, which are part of the Gazprom Mountain
Resort. The object is located in a seismically dangerous area, which increases
the risk of the formation of dangerous geological processes. The requirements
for the device of engineering protection measures increase, there is a need for
calculations of the structure for seismic impact. The paper considers two types
of anti-landslide protection structures – two stages. The first stage is the
"Initial state of the object" – the construction of a cableway
station, the construction of a retaining Wall-3, the fixing of the slope by
anchor fields and the fixing of Wall-3 by anchors through the construction. The
second stage is the "Reconstruction of the engineering protection
system" – the installation of new retaining walls lower down the slope. Numerical
modeling was performed by PLAXIS 2D. The stability calculation was performed
for a different combination of engineering protection options, the calculated
safety factors were compared with the normalized value of the slope stability
coefficient for numerical modeling. In results of the work made conclusions and
recommendation.
