APPLICATION OF INNOVATIVE MATERIALS IN MODERN HYDROTECHNICAL ENGINEERING

When designing of berthing structures (quay walls), the determination of the pressure of reinforced backfill soil plays an important role. The ability of berthing structures to withstand loads depends on many factors, including their age, mode of operation, changes in the characteristics of construction materials, soil bases over time and others. In some cases, the ability to withstand loads decreases significantly over time, while in other cases it increases significantly. Sometimes, the ability of the structure to withstand loads increases during the first period of operation, and then decreases. In some cases, on the contrary, it decreases in the initial period, but then increases. Therefore, it is not possible to establish the actual value of the bearing capacity of structures only theoretically due to the lack of information about the technical condition at this stage of operation, as well as the difficulty of identifying the actual picture of the interaction between the structure and the grounded medium. This task can be solved through experimental and theoretical studies. It is essential to investigate the stages of development and market introduction of innovative materials in the field of hydraulic engineering, to justify the possibility of increasing the reliability and the load-bearing capacity of corner-type structures with a buttress during reconstruction with the use of geotextile materials. These structures were built in the past and require modernization and reconstruction. The issue of reconstruction of corner-type structures with a buttress is relevant for Ukraine ports. Currently, there are no unequivocal methods of determining the effectiveness of berths reconstruction due to the complexity of the task given to the number of variables. The article describes the determination methods of the reinforcement effect by geotextile material; developed models taking into account not only the structure and characteristics of the geotextile materials but also its location in the ground mass. Therefore, the model considers both the parameters of the backfill soil and the geomaterial characteristics and the depth of their embedment.
