Temperature Stress Analysis for Concrete Dam of Jiangya Hydropower Station

Abstract:

Temperature is one of the main loads of concrete dam, adverse temperature load can lead to the dam body cracks, this paper study temperature load’s influence on concrete gravity dam. This paper use finite element method, it adopts finite element calculation software to establish concrete gravity dam’s finite element model of Jiangya hydropower station. Based on monitoring data of water temperature, air temperature, dam body temperature, foundation temperature about Jiangya hydropower station, calculates and analyzes temperature field of dam during operation period, researches stress variation law of dam under the influence of temperature field. The results showe that, temperature load has a great influence on the dam operation, but dam still meet code design requirements; when continuous high temperature during summer, dam should avoid operate under high water level; when continuous low temperature during winter, dam should avoid operate under low water level. Research results provide theoretical according for concrete gravity dam’s safe operation of Jiangya hydropower station.
