Visual evaluation of the condition of sites of location of linear objects of the Khasyrei deposit
When conducting visual observations, the main criteria for assessment of their sites of location’s state should include: the degree of chemical contamination and / or mechanical cluttering of the riverbed and the banks, the floodplain and valley slopes, the water-shed surface; the dynamics of geological-engineering process in the studied area; visible deformations of the linear objects. Comparison and analysis of data received in the process of visual inspection of the waterway crossings allow us to state out that all sites have the same common problem, which is the development of the erosion process on the natural slopes, or on the slopes of the roadway and of the road ditches. The most dangerous areas for the linear part of the pipelines are those that are characterized by complex stress conditions, including longitudinal slopes in the zone of exogenous process action, transitions through the waterways and marshes, and curvilinear sections.
