The experience of examining small culverts artificial structures, carried out by a number specialized organizations, shows that on some highways the country up to 80% pipes have degree damage. This article provides data from field surveys located main Tatarstan. Survey is needed identify common problems at concrete in Field were also analyzed using statistical software factors contributing degr...

The connection joint of prestressed concrete pipe piles is a typical steel–concrete structure, and its bending strength has evolved into critical factor affecting the safety supporting structures in underground engineering. Based on full-scale tests five specimens large-diameter reinforced (PRC) joints, as well corresponding finite element numerical simulation, bearing deformation characteristi...
