Safety state analysis of hydro-engineering structure “Bobrowice I” on the Bóbr river

In the paper the results of carried out technical state and safety opinion of hydro- engineering structure “Bobrowice I” on the Bóbr river were presented. The attention have been paid on the structure exploitation conditions and capacity ability of the weir and the bottom outlet. Problem of sedimentation of the upper reservoir was considered. It was suggested that not every the safety limit is the technical state of the main structure such as weir or the dam. Sometimes its limit are determining by quite different conditions such as lack of possibilities to open the bottom outlet or carrying out reconditioning works on the structure. The influence of such situation on the safety of structure and potential treatment on the ground lying below, was underlined. ...

Safety state assessment of fall stage Krępa on the Odra river

In the paper the results of investigations and measurements are presented, carried out for the aim of technical state assessment and safety of fall stage Krępa on the Odra river. Range and methodology of works for fall stages of low head as-sessment are described, elaborated in the Institute of Geotechnics and Hydrotech-nics of Wrocław University of Technology. Problems analyzed during measure-ments and investigations carried out on the studied barrage are discussed. The final conclusion concerns the safety state assessment of investigated object. In the recapitulation a necessity of research for technical state assessment of hydro-engineering structures is emphasized, being of great importance not only for the safety of investigated object but also for areas situated downstream.     ...
