摘要
根据某客运专线隧道洞口位于半山腰黄土陡壁上的情况,对比了洞口场地回填进洞、沿坡脚修便道进洞、横洞进洞三台阶出洞及横洞进洞小导洞出洞四种方案,并对四种方案的从安全性、环境影响、工期、费用四个方面进行对比分析、打分,最终选定了横洞进洞小导洞出洞方案,并成功运用于兰山隧道进口进洞施工,以期为类似项目提供借鉴。
According to the situation that the tunnel entrance of a passenger dedicated line is located on the steep wall of the loess hillside,four construction schemes are compared,and scored from the aspects of safety,environmental impact,construction period and cost.Finally the horizontal hole entrance small guide hole exit scheme is selected,and successfully applied to the entrance construction of Lansahn tunnel,in order to provide reference for similar projects.
