The finite and element method of calculation of deforming of undergroundtunnel lining, interacting with dry soil is constructed. For interaction simulation between elements of estimated area the special "contact" terminal element, allowing considering all cases of interaction of contacting surfaces is used. A number of tasks of deforming of a ringlining of a tunnel of the subway, including consisting of the separate units contacting among themselves, located in soil is solved. Need of the solution of the contact task for simulation of interaction of concrete units of a ringlining is shown.
