摘　　要：特长隧道施工辅助通道的位置选择非常关键,合理选择施工通道可有效增加主洞掘进工作面,最大限度利用资源配置。主要从通道长度、坡度、总工期、施工排水、工程造价等方面进行了优化分析,优化后的施工通道纵坡减小、造价降低、工期提前,实现了“安全、优质、经济、快速”的建设管理目标,优化思路可为特长隧道施工建设提供参考。The location selection of auxiliary channels for the construction of extra-long tunnels is crucial.The reasonable selection of construction channels can effectively increase the excavation face of the main tunnel and maximize the resource allocation.The optimization analysis is mainly conducted from the aspects of channel length,slope,total construction period,construction drainage,engineering cost and etc.The optimized longitudinal slope of the construction channel is reduced,the cost is reduced,and the construction period is in advance,so as to achieve the construction management goal of"safety,quality,economy,and speed".The optimization ideas can provide reference for the construction of extra-long tunnels.
