Raising of a heavy semi-circular vault on a rigid centering

The modelling of a process of a semi-circular vault raising on a rigid cylindrical centering is conducted. Within the bounds of accreted solids mechanics the evolution of the vault stress-strain state under gravity action during the raising and after its completion is investigated. The vault material is described with defining relationships for elastic or aging viscoelastic materials. The formulation of the non-classical quasi-static initial-boundary accretion problem is given. Its analytical solution in series and quadratures is built. An effective method of calculation of residual stresses in the finished vault after supporting centering removing is offered.
