摘要
长征隧洞是沁水县杏河定都段河道裁弯取直后修建的行洪隧洞,建成以后不能满足50年一遇的防洪标准,给沁水县城的防洪安全带来了严重的挑战,为了提高隧洞的过洪能力,在多种方案比较的基础上,提出了改造原洞、增建新洞的设计方案。
The Changzheng Tunnel is the tunnel for discharging flood,which was builded by Qinshui county after Cueved Cut-off works in Dingdu reach of Xing River had been constructed.The flood control standard of Changzheng Tunnel can’t meet 50-year frequency flood.It brings serious challenge to the flood control safety of Qinshui City.In order to increase the flood carrying capacity of the tunnel,by afternatives comparison,this paper puts forward the design scheme of reconstructing the old tunnel and constructing the new tunnel.
