Theoretical investigation of a composite shell structure for a circular cross-section liquid containment wall

Abstract

In the present research, we investigated the application of flexible hose-like walls, typically with a plastic-fabric composite shell, filled with fluid (typically water), where the level and extent of a relatively large mass of fluid (primarily water) needs to be flexibly and temporarily controlled. Special cases such as expansion of storage capacity (surface and open reservoirs), water level regulation, prevention and prevention of ecological disasters, creation and preservation of water habitats are particularly relevant. The important parameters to be considered in the analysis of a hose-like wall are static and dynamic effects and elastic deformation effects, which together may cause the wall to move horizontally, or even to rise and underflow considerably. Conclusions on their applicability are established on the basis of the results of analytical and numerical studies.
