东非某水电站进厂主交通洞开挖施工关键技术

Key Technology for Excavation of Main Access Tunnel of a Hydropower Station in East Africa

摘要: 东非某水电站进厂主交通洞作为该水电站的主要交通运输通道，其洞长长、净断面宽，且地质、水文环境较差，以致开挖施工难度大、安全风险高。对此，本文结合该项目施工实际，就进厂主交通洞开挖施工关键技术展开细致探讨，以供类似项目借鉴参考。

Abstract: The main access tunnel of a hydropower station in East Africa is the main transportation channel of the hydropower station. The tunnel is long, the net section is wide, and the geological and hydrological environment is poor, so that the excavation construction is difficult and the safety risk is high. In this regard, combined with the construction practice of the project, this paper makes a detailed discussion on the key technologies of the excavation and construction of the main access tunnel into the plant, for reference.
