摘要
结合最新国内外泄流结构振动反演与安全控制指标相关研究成果和相关工程实例,从泄流结构材料参数振动反演、振源识别及泄流结构振动安全控制指标等三方面综述了泄流结构振动反演及安全控制指标的最新研究进展,总结了当前泄流结构振动安全的关键问题;指出今后泄流结构振动反演与安全控制指标研究可围绕泄流结构材料参数反演数学模型和其求解算法创新、泄流结构振源荷载时域识别和等效荷载处理技术创新、泄流结构振动疲劳安全控制标准和人体舒适度综合评价方法创新等几个方面开展。
Combining the latest domestic and international research results with related engineering cases,the updated research progress on the vibration inversion and safety control index of discharge structures were reviewed from the aspects of dynamic inversion of material parameters,vibration source identification and vibration safety control index of flood discharge structures.The key issues of vibration safety for current flood discharge structures were summarized.It is pointed out that the future research on vibration inversion and safety control index of flood discharge structures should be focused on the innovation of the mathematical model of material parameter inversion and corresponding solving algorithms,the time-domain identification of vibration source load and equivalent load processing,the vibration fatigue safety control standards and comprehensive assessment methods of human comfort.
