The authors of the paper present computational models of pile foundations with account for the effect of their interaction with the soil media, as well as the design parameters of integral stiffness of the soil environment contacting the pile sole surface that has round or rectangular caps.
The authors' assumptions that serve as the basis for the identification of the integrated response of the soil media to the contact surface of the pile are as follows:
there is no full soil-to-pile contact whenever tensile stresses are formed on the walls of the side surface of a pile, as the soil does not work in tension;
in the course of the vertical travel of piles along their longitudinal axis over the perimeter of their side surface, soils are subjected to simple shear, whereas the pile sole is subjected to compression;
in the course of the travel of piles having rectangular cross sections in the horizontal direction in the soil media, soil shear is formed in the two opposite side surfaces. The front wall of the side surface is subjected to compression in the direction of the pile travel, while soil is separated from the opposite side surface of the pile shaft;
the pile travel in the horizontal direction causes simple shear of the pile sole.

Subject: friction piles are calculated by the first and second group of limit states. The article describes a new method for friction pile design by the second group (by settlement) of limit state in relation to the pile foundations of buildings and structures in the urban area and in the design of extensions to existing buildings in which the value of settlement is limited or unacceptable. A new method of piles settlement calculation is different from existing method by the Building Code SP 24.13330.2011. The method is based on a new approach of the pile behavior in soil base, which is different from the existing regulations and science papers. Research objectives: the new method of pile settlement calculation is presented with the purpose of clarifying the calculation of pile bearing capacity unlike an existing method in the Building Code (SP 24.13330.2011). The basis of the design is a new idea of the pile behavior in the soil base, which differs from the existing approaches. Materials and methods: the method consists in the formation of the pile settlement only as a result of pile shortening from the compressive force by the deformation of the pile material. Results: the design equation is presented for calculation the pile settlement caused by the pile material deformation. The condition for determining the pile length is presented, which provides the pile settlement only due to the pile material deformation. Conclusion: such approach of the pile settlement calculation is necessary for the design of extensions to existing buildings, as well as new structures near existing buildings, in which the settlement value is already close to the ultimate value of settlement. The article presents the examples of pile settlement calculations obtained by various methods (including the method of the Building Code SP 24.13330.2011) for comparison of the results. The article can be used in the piles design and in the formation of new design standards for pile foundations of structures and machines.

The paper presents pile strip foundations in the areas with karst risk. The analysis of karst hole formation mechanism shows the lateral soil pressure on the piles caused by the downfallen soil on the hole rims, which transfers around the hole edges during karst hole formation. In this case, the horizontal pressure of the pile reactive force in the area of the pile connection with the raft is transferred to the raft. Pile failure at the hole boundaries will lead to the increase of the raft bearing distance above the karst hole. The inadequate raft bearing capacity can provoke the emergency situation. The existing Codes on karst protective foundations design do not contain the analysis of pile and raft horizontal pressure under the downfallen soil.The goal of this work is to develop the method of pile strip foundations analysis in the areas with karst risk in case of karst hole formation. The analysis of stress-strain state of the system “foundation soil — pile foundation” was carried out using numerical modeling in geotechnical program MIDAS GTS. As a result of numerical investigations, the diagrams of lateral soil pressure onto the piles and the raft are plotted. The pile pressure is approximated with the linear or bilinear function in dependence on geometrical dimensions of the karst hole and strength characteristics of soil that generates the horizontal pressure.In the Codes, the analysis of a pile under lateral soil pressure is given for a pile with the free end. In the problem examined, the pile head has the hinged bearing in place of the connection with the raft. In view of the given boundary data, the pile design scheme is plotted. The inner forces and displacements of the pile are determined by integrating the differential equation of a pile bending. The consistent integrations are evaluated out of the boundary conditions. The boundary values of inner forces and displacements are evaluated from the equality conditions of displacements and inner forces in the pile at the level of the hole bottom that are evaluated in turn for the upward and downward pile section. The method of pile analysis is developed in case of lateral soil pressure approximation with the linear function.The method worked out allows recalculating a pile being at the edge of the karst hole and accepting the lateral pressure of the downfallen soil on the hole edges.

The article deals with the questions of designing the foundations for the Oil Pumping Station-2 site of “Kuyumba — Tayshet” trunk oil pipeline. The problems of choice and grounds for technical solutions are considered basing on the results of complex thermo-technical calculations.
The construction territory of OPS-2 site of “Kuyumba — Tayshet” trunk oil pipeline is characterized by complex engineering and geocryological conditions:
1) presence of permafrost soil on 80 % of the site area;
2) absence of sufficiently widespread rocky soils under designed buildings and constructions;
3) transition of loamy grounds into yield during thawing.
The buildings and facilities are designed on the basis of pile foundation type with high rigid foundation grill. The piles’ diameter is 325 mm and 426 mm, the total length of piles is 9—12 m. The full designed vertical loading, transferred to the pile, is ranging from 10.6 to 50.4 tf.
According to the results of the calculations, in order to provide the necessary bearing capacity of piles, securing the perception of transmitted designed loadings, the equivalent temperature of the soil along the side surface of piles (Te) should not be higher than –0,5 °C. Taking into account that the soil temperatures on the projected site mainly range from –0.1 to –0.3 °C, in order to lower their temperatures to the calculated values ventilated underground areas are arranged under the buildings and facilities and seasonally active cooling devices (soil thermal stabilizers) are installed.
Assembly technique and construction of ventilated underground areas with application of soil thermal stabilizers were developed earlier while designing the pipeline system “Zapolyarye — Oil Pumping Station Purpe”.
For confirmation of the accepted decisions forecasting thermotechnical calculations were performed with the use of a special computer program TermoStab 67-87, which allows simulating the changes of temperature regimes of the permafrost in the process of construction and operation of the facility.
As a result of thermo-technical calculations, in case of operation of ventilated underground areas only, in the foundation of the facilities at the OPS-2 site (without the application of thermal stabilizers) a reduction in temperature of frozen soils is predicted, however, the required design temperatures, necessary for providing the bearing capacity of piles (–0,5 °C on their side surfaces and below), in one cold season cannot be achieved. For the areas of the distribution of the confluent type of the permafrost the necessary temperatures are achieved only by the 5th year of operation, and for the areas of distribution of non-confluent type of permafrost such temperatures are not achieved even by the 10th year of operation. A joint operation of the ventilated underground areas and soil thermal stabilization systems is conductive to the reduction of soil temperature of the buildings and facilities’ foundations up to the required values, which secure the load-bearing capacity of piles for one cold season.
