technical portal dedicated to co-production and history of its creation character of plots depending on the type of load formula of force for calculating lining vertical workings in section from the plot of moments in the main system: coefficients of canonical equations: values ​​of unknown angles of rotation of nodes: formulas of force for calculating lining vertical workings in section of plot of moments in the main system: coefficient Actors of the canonical equation: formulas of effort to calculate vertical workings lining in sections from any number of identical contours. system of canonical equations: equilibrium equations of intermediate nodes are equations in finite differences, and the first and last should be considered after replacing the values ​​of the coefficients in the intermediate one - linear homogeneous second order finite difference equation with constant coefficients. its general solution is found in the form: zi = λi. then the characteristic equation is: then the general solution takes the form: the constants c1 and c2 are determined from the boundary conditions, which, taking into account
