浅析各级围岩的隧道工程造价

Analysis on Tunnel Cost of Surrounding Rock at All Levels

文中以大庆至广州高速公路粤境连平至从化段上坪隧道为背景,根据设计资料对不同条件下的隧道进行工程造价的分析探讨,获得了各级围岩的隧道工程造价情况,分析结果表明各级围岩的隧道工程造价指标相差较大。本文的分析结论可以为其他同类型项目合理控制隧道工程造价和正确选择深挖路段的建设方案提供参考借鉴。

Take Shangping tunnel of Daqing to Guangzhou highway Lianping to Conghua section as background.According to design data,this paper analyzes project cost of tunnels under different conditions,then it got as tunnel costs of surrounding rock at all levels.Results showed that tunnel costs of surrounding rock at all levels differ greatly.The conclusion of this paper can provide references for reasonably controlling tunnel cost and correctly selecting deep cut roads of other similar projects.
