An analysis of the problems of ensuring the reliability and durability of hydraulic structures of transport construction from road culverts in operational conditions was carried out. Methods of calculation of hydraulic structures of transport construction from road culverts for static and dynamic loads when interacting with soil fill have been developed. A method of a statistical approach to solving multifactorial tasks of the researched processes was obtained and algorithms for obtaining statistically stable multifactorial simulation models were developed for an ill-defined initial set of experimental data. A statistically stable simulation model has been developed, which allows to predict the kinematic characteristics of the flow in the diversion channel and to study the influence of the structural elements of the lower biff of the hydraulic structures of transport construction from road culverts on the kinematic characteristics of the discharged flow. The requirements for the processes that form the durability of hydraulic structures of transport construction from road culverts are defined. Experimental studies of the hydraulic work of the structure of the road culvert under different conditions of its filling with water were carried out. Experimental studies of the influence of static and dynamic loading and temperature and climate effects of the environment on the operation of a road culvert have been conducted. The main principles of calculation and design of the bottom beef of hydraulic structures of transport construction from road culverts have been developed on the basis of the use of a developed new type of excessive kinetic energy extinguishers - active type energy extinguishers Practical recommendations have been developed for increasing the durability of hydraulic structures due to the optimization of the design based on the sim Product Description popup.authors Yevseychyk Yurii B.
