摘　　要：洞坪水电站地下厂房因受诸多因素影响,采取了一列式布置方式,给地下厂房的通风系统设计带来了困难,为此设计人员针对岩体特性、厂房结构及电站设备发热特点,提出了优化设计方案。该地下厂房进出交通洞为一进一出,属较为节省的布置方式。采用如下设计方案:①利用长交通洞进风去湿;②利用夹墙分配风路;③利用拱顶汇集排风;④利用第二交通洞排风。设计方案紧凑、布置合理,较好地解决了厂房各部位的通风问题。The design of underground powerhouse of Dongping Hydropower Station is affected by many adverse factors, and its one -line layout causes difficulties in the ventilation system design. We conduct a research on the ventilatiori system design and develop an optimized design scheme in the light of rock performance, powerhouse structure and heating characteristics of equip- ment. The layout of access tunnel of the powerhouse is economical with only one way in and out. The following design scheme is adopted： （1） using long access tunnel for dehumidification; （2） using jacketed wall to allocate ventilation circuit; （3） using vault for air exhaust; （4） using second access tunnel for air exhaust. Due to the reasonable design layout and tight arrangement, the ventilation problems of every part of the powerhouse are successfully solved.
