A Methodology for Optimal Layout Design of Pressure Cells for Concrete Faced Rockfill Dams
Onur Ari,A. Melih Yanmaz 대한토목학회 2018 KSCE JOURNAL OF CIVIL ENGINEERING Vol.22 No.8
In this study, a methodology for optimal layout design of pressure cells for concrete faced rockfill dams is developed. Arepresentative dimensionless stress distribution model was formed for obtaining the magnitudes and location of different stress zonesas a function of dam height. This information enabled development of a procedure for proper location and the number of pressurecells throughout the dam body. A vertical placement algorithm based on error minimization was first developed, which is followedby an approach to find the number and location of pressure cells on a particular elevation of the dam body. The effects of face slabcracking and earthquake are interpreted. Furthermore, the performance of the proposed model was also tested when instruments areinstalled to different elevations in the dam body than those recommended by the model developed. The proposed optimizationscheme provides a basis for economical layout design of pressure cells with sufficient information allowing realistic assessment ofthe structural behavior. The application of the proposed model is illustrated for some existing dams. It is observed that this algorithmgives satisfactory results.

A Study On Dam Instrumentation Retrofitting
A. Melih Yanmaz,Onur Ari 대한토목학회 2011 KSCE JOURNAL OF CIVIL ENGINEERING Vol.15 No.2
Continuous monitoring and inspection of large dams would provide means for proper rehabilitative actions to be taken on time which intend to maintain the desired safety throughout the physical life of dams. Comprehensive inspections can be carried out using a number of instruments. An ideal dam instrumentation system should provide time-dependent information about critical parameters so that possible future behaviour of the structure can be predicted. Numerous of the existing dams do not have adequate instruments or current instrumentation systems may not be in good condition. By implementing the modern equipment to existing dams, the uncertainty associated with the impacts of aging or unexpected severe external events will be reduced and possible remedial measures can be taken accordingly. This paper addresses the concept of instrument retrofitting to an unmonitored structure,Gokcekaya Dam, 159 m-high arch dam, Turkey, with reference to investigation of the current condition of the structure. The deficiencies observed are listed and the corresponding rehabilitative measures are suggested. Finally, different alternatives of a new instrumentation system are introduced and compared in monetary terms.
