为了解决菏载平稳二项随机过程组合方法在求解时段组合幅值的最大熵概率密度函数时求解高度非线性方程组计算复杂，不便于实际工程应用的不足．本文根据荷载时段组合幅值的概率特点，以两参数的极值I型来描述其概率特征，建立了简化的组合方法．根据数值模拟试验和实测风浪资料计算结果表明本文极值I型与最大熵分布都能很好的描述时段组合幅值的概率特征，并且具有一致性；当计算不同重现期极值组合荷载时，本文简化方法计算的结果偏于保守．

英文摘要：

Aimed at the complex calculation for the combination method of stationary binomial process of loads in solving the maximum entropy distribution of load, a simplified combination method is presented by describing the probabilistic property of the extreme value of combination loads in time interval through the Extreme I Distribution with two parameters. The calculating results with numerical simulation data as well as observed wind and wave data indicate that both the Extreme I Distribution and the maximum entropy distribution can describe the probabilistic property of the extreme value＇ of combination loads in time interval, and they are identical each other. But in the calculation of the extreme values of combination loads in different return periods, the calculating results obtained with the simplified combination method are little larger than those obtained with the original combination method.
