导流建筑物

基于遗传算法的施工导流建筑物优化

Optimization Based on Genetic Algorithms for Construction Diversion Structures

施工期对导流建筑物等级，施工时段划分，各时段导流方式，导流标准、导流程序和导流建筑物等进行了优化。

The paper gives a presentation in its first part of the overall design conception of grade determination of the diversion structures , division of their construction stages and diversion approaches at each stage , diversion criteria , diversion procedures and diversion structures .

导流建筑物级别为4级。

The grade of the diversion structure s is ⅳ .

各期导流建筑物各异，施工方法也不相同。

All the stages are different and so the diversion construction methods are different too .

趋向较高水头截流，采用较高水头截流，可减少导流泄水建筑物的工程量；

Closure with a high water head can reduce the cost of the diversion engineering .

导流泄水建筑物泄流可靠性分析

Reliability analysis on discharge of diversion structure

论述长洲水利枢纽一期工程的导流标准、导流方案、导流建筑物布置和设计等。

The paper disserts the diversion standard , the diversion scheme , the layout and design of diversion structures etc.

施工导流标准的选择应能明确反映导流建筑物的使用年限

The choice of Construction Diversion Standard Should clearly Involve the Service Life of a Diversion Building

水电工程施工导流的成败直接影响到主体工程的建设，与导流标准选择密切相关，而导流标准的择优必须综合协调导流建筑物的建设投资、工期、系统风险率及其风险损失。

For a hydropower project , river diversion planning directly decides the dam construction and has a bearing on the diversion standard . The relations between selection of diversion standard and investment , construction duration , risk and its losses of diversion structures should be coordinated .
