В статье приводятся результаты натурных и расчетных исследований железобетонных конструкций щитовой стены здания ГАЭС и батопорта сухого дока, которые являются ответственными конструкциями и от состояния которых зависят строительство и эксплуатация ГАЭС и сухого дока. На основе данных проведенных обследований был установлен характер трещинообразования в щитовой стене здания ГАЭС и в лицевой стене батопорта (обращенной в сторону сухого дока). Определены действующие нагрузки и причины образования трещин. Разработаны и практически реализованы мероприятия по усилению щитовой стены здания ГАЭС углеродными тканями, предложены мероприятия по усилению стен батопорта. //The article presents the results of full-scale and computational studies of reinforced concrete structures of the shield wall of the PSPP building and the fl oating bulkhead of the dry dock, which are important structures, on the condition of which the construction and operation of the pumped-storage power plant and the dry dock depend. Based on the survey data, the nature of crack formation in the shield wall of the PSPP building and in the front wall of the floating bulkhead (facing towards the dry dock) was established. The acting loads and causes of crack formation were determined. The actual stresses in the armature were determined by the «valve unloading» method. Fines were cut down in concrete, the studied rod armature was bared, on which deformometers were installed and zero readings were taken. Calculation studies of the VAT of reinforced concrete structures of the shield wall of the PSPP building and the dry dock floating dam were carried out on the basis of spatial finite element models, including the structure and the base. The measures to reinforce the shield wall of the PSPP building with carbon fabrics were developed and practically implemented; the measures to strengthen the walls of the floating bulkhead were proposed.
