The increase in freight traffic between central and northern European countries and the countries of the Black Sea coast requires an increase in shipping along the Danube River. The Danube is the seventh international transport corridor, which unites the countries of Europe and Asia. The deepening of the Bystrii estuary of the Kiliya’s delta of the Danube ensures the implementation of the transport route between the Danube and the Black Sea. The protection of the Marine channel of the Danube-Black Sea deep-sea passage from sediment during storms is provided by a protective dam. The purpose of the research is to study the peculiarities of the wave action on the fragments of an existing protective dam, determine the effective means of its protection and develop recommendations for creating a dam design that is resistant to storm loads. The results of numerical and physical simulation of wave loads on a protective dam of the Marine channel of the Danube-Black Sea deep-water passage are presented. Experimental studies were carried out to study the features of the wave action on a fragment of the dam model. The integral and spectral characteristics of the pressure field on the streamlined surface of the dam model are obtained for the conditions of the passage of storm short and long waves. The features of the wave motion transformation near the dam and the characteristic regions of the frequency spectrum of the wave pressure on its surface are shown. Studies have been carried out to determine the sustainable structure of the dam and a step-like dam with two berms that can withstand storm loads is proposed.

中欧和北欧国家以及黑海沿岸国家之间的货运量增加，要求沿多瑙河的运输量增加。多瑙河是连接欧洲和亚洲国家的第七条国际运输走廊。多瑙河基里耶三角洲的比斯特里河口的加深确保了多瑙河和黑海之间的运输路线的实现。保护性大坝可保护暴风雨期间多瑙河-黑海深海通道的海洋通道免受沉积物的侵蚀。该研究的目的是研究波浪对现有保护性大坝碎片的特殊性，确定保护性大坝的有效手段，并提出有关创建能抵抗风暴载荷的大坝设计的建议。给出了多瑙河-黑海深水通道海洋通道防护坝上波浪载荷的数值和物理模拟结果。进行了实验研究，以研究坝模型片段上的波浪作用特征。在暴风雨短波和长波通过的条件下，获得了大坝模型流线型表面上压力场的积分和频谱特征。示出了坝附近的波浪运动转换的特征以及波浪压力在其表面上的频谱的特征区域。已经进行了研究以确定大坝的可持续结构，并提出了具有两个可以承受暴风荷载的护堤的阶梯状大坝。
