Abstract
Аt action on the rail of forces vertical and lateral there is its bend in a plane vertical and horizontal and its twisting. The reactions of the rail fastening and reactive croutni vertical and horizontal are the constituents of reactions of rail supports moments. Therefore in the given work is examined vertical and horizontal transversal inflexibilities of fastening to the type CPP-5-5 at bends and his inflexibility at twisting of rail. Rozrahovouyochi action of these forces, it is needed to take into account the elements of resistance of subrail gasket to squeezing action. By means the calculations it was led to, that an equilibrium in the knot of fastening would be when final assembling forces of the terminal pinning will equal resilient resistance of gasket of compression. But studying action of forces vertical and lateral in fastening, it is impossible not to take into account horizontal transversal inflexibility of fastening, which arises up under action of lateral force, and also inflexibility, at twisting. As a result of calculations the inflexibilities of knot of fastening to the type CPP-5-5 mathematical to dependence are Got at vertical and horizontal bends and twisting of rail under action of lateral forces as functions of inflexibility of resilient elements of fastening.
