新建排洪隧洞工程围岩参数及衬砌设计研究

RESEARCH ON SURROUNDING ROCK PARAMETERS AND LINING DESIGN OF NEW FLOOD DISCHARGE TUNNEL PROJECT

为解决排洪隧道建设过程中地质条件复杂影响稳定性的问题。本文以木里县梭罗沟金矿新建排洪隧洞工程为例,首先对隧洞工程地质条件进行了分析评价,然后将隧洞围岩分级及各级物理力学参数进行了试验分析,以掌握围岩的岩土力学参数,最后根据对新建排洪隧洞洞身进行了设计。该设计可以有效的支撑后续工程施工,保证施工过程的安全。

To solve the problem that the complex geological conditions affect the stability during the construction of flood discharge tunnels,The geological conditions of the newly-built flood discharge tunnel project at Suoluogou Gold Deposit in Muli County were analyzed and evaluated.Then,the surrounding rock of the tunnel was classified,and the physical and mechanical parameters of each level were tested and analyzed to grasp the geotechnical parameters of the surrounding rock.Finally,the newly-built flood discharge tunnel was designed,which can effectively support subsequent construction projects and ensure the safety of the construction process.
