| Title of the article | Hydraulic calculation of silted culverts |
| Abstract. | The article presents the main provisions of the hydraulic calculation of the silted pipes of round and rectangular cross-section. Silting of headwater culverts is quite a common phenomenon in the practice of exploitation of motor roads. Therefore, the question of calculating silted culverts able to skip the current flood, is of great practical importance. Silted constructions work differently, than clean pipes. Assumptions and adjustments adopted in the calculations allow to take the hydraulic calculations for silted structures. Calculations were carried out for different levels of silt pipes. The final results were used to without size mind. As a result of the graphics bandwidth of round pipes of various diameters matched that says about the correctness of the chosen assumptions in the calculations. Special attention should be paid to 30% silting of pipes, in which the change of the hydraulic regime of work with the gravity of the semi-pressure head operating mode. This entails additional costs on the strengthening of slopes embankment and may affect negatively to the operation of the pavement, causing frost heave. This article gives the opportunity to predict the work of flume pipes for the different measure of silting and identify the likelihood of negative consequences from the operation of silted structures. |
