Description
The article looks at the current state of energy in Vietnam and the selection of new Russian steam turbines for operation in combined gas-steam plant in Vietnam. The calculated results of thermal performance scheme 3x1 with combined gas-steam plant 1090 MW based on the Russian steam turbines K-330-240-2 and on the steam turbines TS2A40 Mitsubishi (station PhuMy-1, Vietnam). It also looks at the influence of the efficiency of high-pressure cylinders of Russian steam turbine K-330-240-2 on the efficiency and power of a gas-steam plant 3x1 with 1090 MW, increasing the efficiency of high-pressure cylinder of steam turbine through the use of honeycomb seals in flow part

FEATURES OF NUMERICAL MODELLING OF LANDSLIDE PROCESSES ON THE EXAMPLE OF THE CITY OF SOCHI
DescriptionDevelopment 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

STUDY OF SOIL MOISTURE FOR LOGGING ROADS
DescriptionThe analysis of the statistical structure of the soil humidity stability and the precipitation-evaporation ratio is represented in the article. The mathematical model of the subgrade humidity forecast allowing evaluating actual or designing humidity of the any soil type with the natural humidification in the range of active layer 2.0 m according to the observed temperature and air humidity deficiency data is worked out

Description
The subjects of study are vertically reinforced bases of high-rise buildings and its behavior in compound sub-soil conditions. The article reviews the carried out analyses of reinforced subsoil for high-rise building in Sochi with particular simulation of combined action for reinforcing elements and nearby surface. Analyses were carried out with such software as PLAXIS 2D, ING+ and MIDAS GTS. As a result of numerical analyses the comparison of raft-pile foundation and slab foundation on reinforced subsoil has been per-formed for seismic regions
