摘要：

The article considers innovative materials for tunnel lining. This paper aims at research of the blocks of tunnel lining, reinforced with fiberglass reinforcement and polypropylene fibers. The research of strength and deformation characteristics of blocks for lining tunnels on the operational loads were carried out in the course of work. The task of the research was to test eccentric compression of two identical blocks of tunnel lining with fixing the basic parameters of deformation under load. Indices for the formation of cracks, fissures disclosure, deformability and strength of concrete non-destructive method using ultrasonic tester had been determined. (C) 2016 The Authors.
