Development of infrastructure of Sochi as mountain resort has demanded increase in transport means of communication and development of territories, difficult for construction. Construction works cover territories of the Kudepsta and Adler districts and also Krasnaya Polyana. The main problems at design near Greater Sochi are landslides and landslide processes and also high seismicity of territories. Besides, the increased technogenic loadings on many sites have led exogenous processes to activization. At unforeseen activization of landslide processes it is required to develop actions for strengthening of the existing constructions or construction of new protective designs in the shortest possible time. However, there are problems of modeling of a landslide situation. On the example of construction retaining at the portal constructions of a railway tunnel near Sochi modeling of landslide processes on the basis of natural observations (monitoring) is considered and also actions for stabilization of slope processes are described
Expansion and increasing of the Krasnodar region
transport infrastructure during the construction of
the Olympic facilities together with the new land
development created a necessity for construction in
the remote areas of landslide slopes with the
complex engineering-geological conditions.
Constructions of bored piles, jammed by in nondisplaceable
soil are often used as one of the
measures for the protection of surface rocks
landslide movement and tightening the slope weak
sections. Such constructive solution is often being
considered the best, and sometimes the only
acceptable solution. When designing engineering
protection it is recommended to consider the use of
a number of active protection activities, aimed at
the landslide processes stabilization. However, in
case of construction production impossibility due to
terms of organization, it is necessary to provide
passive protection which would secure that the
landslide streamlines the construction. Currently,
the mechanism of the soil landslides interaction
with constructions of detached objects spot
protection isn’t studied enough. Known methods
adopt simplifications and assumptions which lead
to definite significant errors in the design of slope
protection structures. Security and reliability of
such structures can only be achieved with the
adoption of high factor of safety values. This leads
to increased material consumption and labor input
for the erection of defensive structures also reduces
the economic efficiency of these structures. In
addition the process of designing protective
structures in the Krasnodar region is further
complicated by fact that the landslide of
construction area is mainly folded by flowing clay
soils
This article describes the practice of conducting a
geotechnical monitoring of the road tunnel № № 8, 8а «Doubler Kurortnogo Prospekta» in Sochi in
difficult geotechnical conditions. Geotechnical
monitoring method was developed on the results of
mathematical modeling performed based on
engineering studies and design solutions. The
particular importance is paid to areas of shallow
road tunnels, because in these areas there are the
highest strain that could lead to malfunction of the
lithological technical system "accommodating array
- fixing tunnel" and the further destruction of the
road tunnel walling. Geotechnical monitoring at the
stage of engineering survey allows us to assess
comprehensively the condition of the geological
environment in a pristine condition, as well as
detailed consideration to the effect on her of
construction of mining operations. Implementation
of geotechnical monitoring at the stages the
engineering survey and construction will identify
weaknesses malfunction of the lithological
technical system "accommodating array - fixing
tunnel" and ensure the security of the operation of
such a technically complex and demanding
facilities such as road tunnels
Currently, there is increasingly reduced number of the sites convenient for construction. In this regard
there is a question of development of new
territories, for various reasons which were earlier
considered economically unprofitable or unsuitable
for construction. Often, for construction in the
mountain area it is necessary to carry out
construction of objects in landslide territories.
However, landslide processes constitute big health
hazard and lives of people and also safety of
buildings and constructions. The main objective of
engineers when performing design and exploration
work on landslide territories is the determination of
stability of slopes and size of landslide pressure
from soil and also identification of the most
dangerous combination of loadings which can
demand design and construction of a construction
against landslide of landslide protection structures
with significant load-bearing capacity. The research
presented in article allows to define the most
dangerous loads affecting the stability of the slope
and also of the selection of a protective construction
(against landslide). Dependences of change of
landslide pressure and coefficient of stability of a
slope are received from action of various loadings
(both static, and dynamic)
