Results of technical diagnostics are given is long maintained water carrying out constructions nondestructive control methods on an example of irrigating systems of the South of Rossi. Possibility of use of devices of nondestructive control is especially noted at inspection them that allows operatively, without additional damages, to receive an objective assessment of their technical condition. When using this approach there is a possibility justification of parameters of defects and damages which it is impossible to establish at visual survey.
Keywords: the hydraulic engineering constructions which are water carrying out channels, nondestructive control methods, modeling, a technical condition.
The influence of non-multi - repeated loads on columns of keramzito fibrobetona. Comparative results of tests Depends on the flexibility of columns, the eccentricity of the external force, the coefficient of reinforcement options and loading. The obtained results suggest that repeated loading nemnogokratno increase the carrying capacity of columns, compared with a single loading. This is especially effective for columns with low flexibility and small eccentricities external force.
Keywords: stand, keramzitofibrozhelezobeton, bearing capacity, nemnogokratno repeated loading, mixed reinforcement flexibility.
