Optimum Arrangement of Strain Gage Rosettes in Concrete Dams
In order to ensure accident-free operation of hydraulic structures exposed to acting loads and affecting factors, continuous field observations and research are carried out with the use of the measuring and diagnostic systems installed. Outline and scope of the field observations and research conducted are governed by regulatory documents, depend on the category of importance of the hydrosystem, its design, geotechnical features of the foundation, and environmental requirements and are determined by the design organization or research institution. Instrumental field observations are conducted at hydraulic structures by means of instrumentation installed during their construction. Due to the accidents and catastrophes that have occurred at dams, strict requirements are applied to instrumentation number and location. Measuring and diagnostic systems are installed in feature points of dam sites, based on theoretical calculations, laboratory research and previously elected similar structures and can be effectively used when conducting research using a common technique by means of standard embedded instruments installed according to a standard layout.
