糯扎渡水电站地下引水发电系统的施工方法

Construction of underground water diversion and power generation system of Nuozhadu Hydropower Station

糯扎渡水电站地下引水发电系统不仅施工难度大,而且施工工期长、干扰多。对其施工通道布置、主要洞室施工方法及施工期通风等施工关键技术进行了分析研究,进而探讨了大型地下洞室群施工的施工方法。

The construction of the underground water diversion and power generation system of Nuozhadu Hydropower Station is difficult and has a long construction period and many disturbance factors. This paper analyzes some key points of construction techniques such as arrangement of construction passage; the construction method of main tunnel chambers and air ventilation during construction period and discusses the construction methods of large-scale underground tunnel chambers.
