摘要
在特长隧道修建中,地下风机房洞室群是整个隧道施工中的难点。文章通过宝塔山隧道地下通风系统洞室群的布置设计、风机房洞室群施工时面临的问题,在满足了通风需要的断面净空要求的前提条件下,并考虑施工方便性,对地下通风系统洞室群布置和洞室断面进行了调整,分析了各方案的优缺点,以及隧道洞室群的设计及洞室的施工方便性相结合的重要性。
In the construction of extra-long tunnels, the underground ventilation chambers are of great importance. This paper discusses an analysis of the cavern layout design for the Baotashan Tunnel as well as problems encoun- tered in the construction of the ventilation chambers. Some adjustments were undertaken to facilitate convenience of construction. Furthermore, this paper addresses the merits and demerits of various schemes.
