We look for the optimum alternative on the basis of analyzing the internal connection of the diffluent piers body style parameters and the wave 在分析分流墩体型参数与波浪间的内在联系的基础上，寻找较优的分流墩方案，并在理论分析的基础上提出一些经验公式。

Using the method which is adopted to optimize the two reservoirs " operation by using the simulation models is on the basis of the order of series s alternative enumerated . the optimization is carried up for the raw water system of changchun water supply system of the alternative group which is formed by restrained in certain order according to different index with the hope of no optimum alternative is omitted . a conclusion can be obtained from the changchun city water supply system ' s long - term projection and the current water supply situation 长春市供水系统的原水系统是由石头口门水库、新立城水库和松花江组成，使用模拟模型对两库运行优化时，采取基于枚举思路的系列方案法，即在约束范围将方案按一定顺序，对不同的指标形成方案组以其不遗漏最优方案对原水系统进行了优化。
