Abstract
The experience of examining small culverts of artificial structures, carried out by a number of specialized organizations, shows that on some highways of the country up to 80% of pipes have some degree of damage. This article provides data from field surveys of pipes located on the main highways of Tatarstan. Survey data is needed to identify common problems at concrete culverts in Tatarstan. Field data were also analyzed using statistical software to identify factors contributing to the degradation of concrete culverts. The article presents a method for assessing the risk of developing negative phenomena when maintaining concrete pipes. The proposed risk assessment method allows predicting and preventing the occurrence of such phenomena.
Highlights
The construction and operation of highways can cause a number of negative changes in the environmental situation in the adjacent territory [1,2,3]
This is especially true for artificial structures, of which small culverts account for 85-90%
The experience of the survey of small culverts of artificial structures conducted by a number of authors and specialized organizations [7,8,9] shows that up to 80% of the listed structures have some degree of damage on individual highways [10,11,12]
Summary
The construction and operation of highways can cause a number of negative changes in the environmental situation in the adjacent territory [1,2,3]. This is especially true for artificial structures, of which small culverts account for 85-90%. During the construction of the roadbed, the natural terrain on the right-of-way is disturbed, and the vegetation layer is removed. All this leads to changes in the surface runoff and water regime of the territory [4,5,6]. One of the factors that cause damage to the culvert, its heads and fortifications, is the silting of the pipe
