摘　　要：水电站地下洞室群在施工期除永久通道外,辅助施工通道也是重要组成部分。本文以双江口水电站引水发电系统为例,简述引水发电系统地下洞室群辅助施工通道布置。双江口水电站引水发电系统地下洞室体形结构大、洞室多,通过布置辅助施工通道,满足地下洞室群“平面多工序、立体多层次”的施工组织要求,可有效解决施工干扰问题,保证施工均衡有序进行,对类似水电工程地下洞室群施工具有参考价值。Assisted construction passage is an important part of underground cavern groups of hydropower station besides permanent passages.The water diversion power generation system of Shuangjiangkou Hydropower Station is adopted as an example in the paper.The arrangement of assisted construction passages of underground cavern groups of the water diversion power generation system is briefly described.Shuangjiangkou hydropower station water diversion power generation system is characterized by large underground cavern shape structure and excessive cavities.The construction organization requirements of underground cavity groups are met through the arrangement of assisted construction passages namely“multiple procedures in the plane;and multiple three-dimensional levels”,thereby effectively solving the problem of construction disturbance,and guaranteeing thebalanced and orderlyconstruction.The paper has reference value for construction of the underground cavities of similar hydropower projects.
