Abstract
The article considers the bending of a long concrete pipeline when its section is raised to the free surface of a reservoir. The initial horizontal position of the pipeline is rectilinear. Its static bending occurs under the action of concentrated forces, the weights of the pipe and the transported medium, and the lifting force of water. The minimum required value of the lifting force and the corresponding length of the raised section of a long pipeline are determined. Taking into account the large ratio of this length to the depth of the reservoir, a linear bending equation is used. An analysis of the bend is given depending on the controlled lifting force and the controlled rise of the pipeline.
期刊介绍：
Mechanics of Solids publishes articles in the general areas of dynamics of particles and rigid bodies and the mechanics of deformable solids. The journal has a goal of being a comprehensive record of up-to-the-minute research results. The journal coverage is vibration of discrete and continuous systems; stability and optimization of mechanical systems; automatic control theory; dynamics of multiple body systems; elasticity, viscoelasticity and plasticity; mechanics of composite materials; theory of structures and structural stability; wave propagation and impact of solids; fracture mechanics; micromechanics of solids; mechanics of granular and geological materials; structure-fluid interaction; mechanical behavior of materials; gyroscopes and navigation systems; and nanomechanics. Most of the articles in the journal are theoretical and analytical. They present a blend of basic mechanics theory with analysis of contemporary technological problems.
