A method and system for determining a limit exceedance of an operating parameter in a steam turbine system.

一种确定蒸汽涡轮系统中运行参数的极限超过值的方法和系统。

Finally, the probability of crack exceedance and structural damage degree are calculated and the durability analysis is completed.

进而分析裂纹超越数概率和结构损伤度，完成结构耐久性分析。

After their discretion, it is possible to obtain the expression and analytical approximation for the annual probability of exceedance.

离散化之后，得到年超越概率的综合表达式及其相应的解析近似。

The live load should be determined that the exceedance probabilities of live load for different design working life equal to that for conventional design loads.

应根据不同设计使用年限活荷载的超越概率等于常规设计荷载超越概率的原则确定活荷的载标准；
