重庆巴山水电站施工导流方案比较

Comparison of River Diversion Schemes during Construction of Bashan Hydropower Station in Chongqing

导流方案的设计比选是施工组织设计的重要部分,对施工安排、工程投资等均有较大影响。依托巴山水电站,介绍了其施工导流的选择标准;从施工条件、工程量、造价等方面比较了两个导流方案的优缺点;在确定的导流方案基础上,依据水力计算成果、工程量及可比投资方面,对四个导流隧洞方案进行了比较,确定了导流隧洞断面方案。

River diversion design scheme selection is an important part in construction organization design , which makes great influence on construction arrangement and project investment. According to practices in Bashan hydropower station , the selection of its construction diversion scheme is described. Advantages and disadvantages of two river diversion schemes are compared in aspects of construction conditions , amount of works and cost . For selected river diversion scheme , 4 diversion tunnel options are compared based on hydraulic computation results , amount of works and comparable investment so as to determine diversion tunnel cross section.
