Tjutjkin O. Theoretical bases of complex analysis of tunnel constructions

The thesis is devoted to the decision of important problem in area of underground construction calculations, namely to development of theoretical bases of complex analysis of tunnel constructions. The decision of task of tensed and deformed state determination of the surrounding array as viscous-elastic-plastic environment the method of division of deformations in accordance with principle of their superposition is offered. Theoretical bases of power approach are developed to the tensed and deformed analysis of the system "tunnel construction - surrounding massif", analytical dependences of energy for elastic-plastic deformation and for the rheological phenomena are got. On the basis of theoretical research of tunnel constructions complex analysis the methods of their static and dynamic researches are developed, thus the complex of loadings includes the mobile loading, shock and impulsive influences, possibility of the making progress bringing down of the station construction is also considered.
