For hydraulic structures of long-term operation, assessments of operating life, limit states and safety of structures are required. The design of reconstruction, restoration of functional parameters of structures is preceded by pre-design inspections of the structure. The relevance of pre-design inspections is the need to assess the characteristics of technical and operating state of the structure, to describe reasons for deviations from design parameters of operation, to obtain recommendations to justify the design of reconstruction, restoration or repair of structures. This article presents the results of a pre-design inspection of a high-pressure lock on the Ufa River. An analysis of the complex of effects on the stress-strain state of the structure, static calculation of the lock chamber wall is carried out considering design changes during the operation period – installation of additional buttresses, vibrodynamic inspection and calculation. The obtained calculation results are compared with data of instrumentation equipment. The purpose of the inspection is to obtain a preliminary design assessment of technical state of the hydraulic structure – lock, including an assessment of the possibility of further operation. The practical significance of the paper is determined by the fact that the results obtained can serve as baseline data for a design of reconstruction, restoration of a hydraulic structure and recommendations for ensuring its long-term safe operation.
