“…As a rule, the soil bed is composed of weak water-saturated floury-clay soils occurring at a considerable stratification depth; they possess low strength and are highly deformable in external loading [1,2]. The traditional strip foundations are not applicable for 12 … 15-storeyed buildings because of low design strength of the soil bed, weak structural bond between separate strips and their response to uneven settlements.…”

Abstract. Authors present the results of studies of innovative foundation structure. The idea of how to increase the operational quality of foundations and reduce the costs due to rational loading of the soil bed is numerically simulated. It is shown that the bending moment in the foundation slab depends on uneven settlements of the soil bed. It is proposed to stabilize the deformable soil bed by the damping layer placed under the slab footing in the zones with minor settlements. Considered is the concept of the damping layer in the foundation slab placed on the soil bed (DLS). The in-situ test for DLS-clayey bed interaction is described. Given are the results obtained after the experiments for DLS performance. The result of DLS implementation in designing the foundation of the 22-storeyed block of flats is considered. The expediency of DLS in comparison to standard foundations is presented.

“…With the advent of geosynthetic materials used as reinforcing elements, it is getting popular to use one of the ways of strengthening the weak clay base with sandy piles reinforced along the contour [1][2][3][4][5][6][7][8][9][10][11][12][13]. Problems with weak clay bases are sufficiently presented in [14,15].…”

“…The lack of a unified algorithm for calculating stress and strain states of the base strengthened with sandy piles reinforced along the contour, makes it difficult to extensively use these piles in a low-rise construction [1,13].…”

Abstract. The paper presents an engineering method for calculating the weak clay base, strengthened with sandy piles reinforced along the contour. The method is based on the principle of layer-by-layer summation, which is used when designing the bases and foundations. The novelty of the suggested method lies in the taking account of the soil reaction along the pile lateral surface and the impact of external vertical loads on the vertical displacement of the base.

Abstract. The paper studies the influence of the oil and gas pipeline on the base of water-saturated soil in terms of external forces effect (from the pipeline). The developed mathematical model of stress-strain state of "the oil and gas pipeline and the grounds" system allows us to identify the maximum load resulting from the impact of a curved section of the pipeline on the base as well as the deformations occurring in the grounds.
