卡鲁玛水电站尾水隧洞施工期的通风设计及应用

Ventilation Design and Application during Construction of Tailrace Tunnel at Karuma Hydropower Station

长隧洞通风散烟是隧洞工程施工的一个难题,通风效果的好坏直接影响到长期从事地下工程施工人员的身心健康和隧洞施工进度。如果没有良好的施工通风设计方案,将严重影响企业形象,甚至因为通风不达标而停工。为解决卡鲁玛水电站尾水隧洞项目施工的通风问题,经过模型分析和严格的理论计算,设计了有效的通风方案,经过该项目的实践验证,通风效果良好,可为类似工程提供参考。

Long tunnel ventilation is a difficult problem in tunnel construction. Good and poor ventilation directly effects emotional and physical health of construction personnel who work in underground project for long time and also tunnel construction progress. If construction ventilation design scheme is not good,not only the company image will be badly influenced,but also the project stops because tunnel ventilation cannot meet standards. In order to solve the problem,effective ventilation scheme is designed after model analysis and strict theoretical calculations. The practice has proved that the tunnel ventilation is good,providing references to the similar projects.
