摘要
本文根据可靠性理论,给出了低淹没度水跃的极限状态设计标准和可靠性表达式,分析了影响水跃淹没度的主要水力因子(流能比K和下游相对水深了)的随机性和相关性,讨论了将相关的非正态变量转换为非相关的当量正态变量的拟合处理办法,论证了用JC方法进行水跃可靠性计算的适用性。
According to the reliability theory based on the probabilistic analysis, reliability expression and limit state design standard of a little submerged hydraulic jump is given, stochastic and related characteristics of main hydraulic factors which affect the submergence degree of the jump is analyzed, the fitted method for transform related non-normal variables into non-related normal one's is discussed in this paper. It is demonstrated that the JC method is available to calculate the hydraulic jump reliability.
