A Methodology for Optimal Layout Design of Pressure Cells for Concrete Faced Rockfill Dams

다국어 초록 (Multilingual Abstract)

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.
