Analysis of the Spillway Lining Cracks of Shuangquan Reservoir

Abstract:

The main causes of the spillway lining cracks of Shuangquan reservoir are temperature difference and shrinkage of concrete. Through the analysis of the causes of the cracks, the maximum tensile stress formula and reasonable expansion joint distance formula of the influence of bedrock on spillway were established under the combined action of decrease of temperature and shrinkage. Taking an engineering project for example, it is proved that the calculated results using these formulas are matched with the measured data basically, which can provide design basis for controlling the cracks of reinforced concrete lining in similar project.
