This paper presents review of author’s researches of thin cylindrical shells of large diameter filled with soil and used in construction of berths, breakwalls, retaining walls, bridge piers, and etc. The theoretical model for soil stability of the researched structures based on soil boundary state of stress solution with allowance for bond slip is developed. Suggested correlation represents a theoretical model that functionally relates parameters of foundation soil and construction sizes with maximum horizontal force, which might be held by a structure without loss of soil bearing capacity. The numerical model of a thin cylindrical shell with infill under eccentric load is developed. Modeling and experimental determination of the interface strength of the contact surface between the infill and the inner surface of the shell is proposed. The details of testing of physical model used for the experiments are discussed. The effects of the interface friction on the shell behavior and on the foundation stresses are investigated. The influence of parameters affecting the interaction between the soil infill and the inner surface of the shell material is determined. It is based on a comparison of experimental results with calculations performed using the proposed mathematical model. The results of experiment are shown in comparison with calculation data’s for proposed numerical model. Effect of ice load on shell structures with infill on compressible soil is also considered in this research. The numerical model is proposed, which takes into account the interaction between soil environment, effect of ice load and thin shell with infill, to predict the stability and durability of shell structures under ice load.
