From these positions durability and remaining resource of the damaged elements of buildings of the long-term exploitation, which are picked up thread on injections technologies, is estimated. Built models lump homogeneous bodies which take into account geometrical and physical non-linearity of deformation of material of filler. On the basis of decision of the proper regional tasks the set limits of applicability of linear models and cases, when it follows to conduct calculations within the framework of nonlinear models. The model of nonlinear deformation of materials near of the thin resilient including and filled crack defects is developed. The formulas simple for the engineering use, and after which it is possible to estimate the degree of renewal of durability of the damaged elements of buildings of the long-term exploitation "healed" of injections technologies are got. Within the framework лінеаризованої of resiliency theory of bodies with initial tensions is developed methods of evaluation of durability of bodies with the filled cracks which are exploited in the conditions of the difficult tense state subject to the condition cyclic loading. Approach is offered for the calculation of period crack origin near of the filled defects.
