摘要
针对什翁隧道原设计采用的明挖法施工,存在安全风险高、国道改路不合理,不能按期完工等问题,提出了暗挖法出洞方案,降低了安全风险,保证了工期,通过经济技术比对分析,优化的方案在工程投资上也节约明显。
In view of the problems such as high safety risk,unreasonable divagation of national highway and delay in completion of open-cut method originally designed for the construction of Shiweng Tunnel,this paper put forward the plan of excavating the tunnel by subsurface excavation method,which reduces the safety risk and ensures the construction period.Through the comparative analysis of economy and technology,the optimized scheme also saves obviously on the project investment.
