Abstract
Systems and methods of determining a tension of an anchor embedded in a dam are described. A dynamic impulse response of the dam is empirically obtained in such that a portion of the empirical dynamic impulse response is dominated by a dynamic behavior of the anchor. Furthermore, a set of modeled impulse responses that map to a set of tension values for the anchor are obtained. Next, a closest matching modeled impulse response from the set of modeled impulse responses that is a closest match to the portion of the empirical dynamic impulse response that is dominated by the dynamic behavior of the anchor is determined. Finally, a tension value from the set of tension values is selected, which is the closest match to the portion of the dynamic impulse response dominated by the dynamic behavior of the anchor. As such, the tension value of the anchor can be determined.
