Abstract
Currently, the search for constructive solutions of berthing and enclosure structures of vertical type, providing a reduction in the reflection coefficient of waves, wave loads on the structures and their bases. To create normal conditions in the part of the wave regime in the Far Eastern port during the reconstruction of the pier-mole, it was proposed to use perforated concrete massifs with a quenching chamber. The use of such structure of a wall in the form of pillar masonry of hollow massifs (without ligation the seams) in the absence of an internal cavity filler as a protective structure has no analogues in our country. The results of operational author’s supervision during the construction of the pier-mole showed that on the commissioned section of the structure there are a significant number of defects – rolls, offsets, turns of individual blocks, etc. This situation has led to the need to establish the actual state of the structure and its elements to identify the causes of defects and damage. For this purpose, design, executive documentation, technical supervision materials, etc. were studied and two cycles (initial and main – control) of engineering surveys of the surface and underwater parts of the operated wall section with a length of about 250 m were implemented. Their results served as the basis for the analysis of the technical condition of the structure and the development of measures to improve its operational qualities. The analysis also used data from experimental model studies of the vertical wall structure under consideration.

Summary
ФГБОУ ВО «Национальный исследовательский Московский государственный строительный университет» Москва, Россия Доцент. В настоящее время ведутся поиски конструктивных решений причальных и оградительных сооружений вертикального типа, обеспечивающих снижение коэффициента отражения волн, волновых нагрузок на сооружения и их основания. Для обеспечения благоприятного волнового режима в порту проводятся исследования по выбору оптимальных компоновочных решений, а также применяются конструкции причальных сооружений, не создающих отраженную волну [1,2,3]. В связи с этим в нашей стране и за рубежом ведутся поиски конструктивных решений причальных и оградительных сооружений вертикального типа, обеспечивающих снижение коэффициента отражения волн, волновых нагрузок на сооружения и их основания. Положительные результаты крупномасштабных испытаний и строительства причалов из пустотелых бетонных массивов в портах Черного моря, их высокие технико-экономические показатели по сравнению с показателями других конструкций гравитационного типа [9], послужили основанием для разработки типовых проектных решений набережных для глубин 6,5–15,0 м и последующего их широкого использования при возведении причальных и берегозащитных сооружений
