Research on the Crack Stability of Dam Concrete Based on the Measured Monitoring Data

Abstract:

This paper proposes a theoretical expression for the ultimate relationship between the crack gauge monitoring data and steel stress gauge ones in dam concrete, based on the equation for crack width of reinforced concrete member, when the cracks expanded to the crack-control steel. In addition, a practical method is developed for analyzing and determining the crack stability of dam concrete, which predicts whether a crack elongated to the crack-control steel or not by comparing the observed values to the theoretical ultimate value. The provided method is proven to be proper to evaluate the crack stability of dam, which is simple and practical.
