混凝土坝应力应变监控指标研究

Study on Stress-strain Monitoring Indicators of Concrete Dam

混凝土坝应力应变监控指标的拟定是一项重要的工作。运用变形法将实测应变值转化成应力值,进而采用遗传算法优化的最大熵理论拟定其监控指标。工程实例表明,该方法简单可行,避免了人为假定分布带来的随机性,能准确地拟定大坝监控指标。

The formulation of stress-strain monitoring indicators of concrete dam is important. The measured strain value is firstly conversed into stress value by deformation method, and then the monitoring indicators are formulated herein by the maximum entropy theory optimized with Genetic Algorithms. A case study shows that this method is simple in practice and successful in avoiding the randomness of artificially assumption. This method can accurately develop the dam monitoring indicators.
