Engineering Guidelines for the Evaluation of Hydropower Projects: Chapter 11- Arch Dams
Federal Energy Regulatory Commission, 2018
This chapter of the Guidelines provides guidance on the criteria and procedures used by the FERC to evaluate the safety and structural integrity of existing arch dams under its jurisdiction.
The material presented in this chapter assumes that the reader has a general knowledge and understanding of the basic principles of arch dams, i.e., how they are designed, constructed, operated, and maintained.
The intent of this chapter is not to mandate new analyses and investigations regardless of whether or not they are needed. Rather, the variety of issues addressed and computation methods put forward are an attempt to anticipate the variety of problems that could be encountered. This chapter should not be interpreted as requiring every test, analysis, and investigation that it describes at every dam. It may well be that for a given dam, specific failure mechanisms suggested in this chapter are not pertinent. Analysis should always be directed at evaluating the viability of potential failure modes. If there are no failure modes of concern, then no analysis is necessary.
