摘要
在海洋工程、水利工程等建筑工程中，合理地确定多年一遇波高、洪水量等，对于建筑物设计的安全和造价问题是十分重要的。兼顾安全和费用两方面的要求，就得在各种各样的计算方法中选择较为理想的方法进行推算。就海浪波高设计而言，
The parameters in Poisson-Gumbel compound extreme distribution are estimated from common methods and compared. The results show that among them the moment method is better. This method, however, is not very perfect, an improved method, the compound moment approach is presented. Actual examples indicate that the presented approach is better than those mentioned above.
