ABSTRACT
Analysis of interaction regularities of large-size reinforced concrete shells at the erection stages in heterogeneous soil mediums allowed to significantly expand the field of their rational use in underground construction parameters and indicators. Strength and deforativeness of a large-size massive structure, its geometrical variability should be calculated not only for the final stage of construction but also for a whole history of driving considering a history of caisson-soil bulk interaction at driving, and, consequently the effect of gradual inheritance of stress-strain state. The methodological approach proposed in the paper allows transferring from the earlier accepted methods of calculation of underground caisson structures to the concept of simulation and prediction of defectless lifecycle at the stage of construction. Modeling and calculative substantiation of schemes and parameters of preventive protection of an underground structure at the stage of its construction using geotechnical methods provides its safety and resistance against technically generated impacts.
