摘要
山西省东山供水工程某输水隧洞位于黄土丘陵地区,为沟谷冲积区,土体中砂、砂砾石、淤泥填充现象显著,并且存在渗水、涌水问题,在施工过程中掌子面发生连续塌方导致隧洞冒顶。根据地质情况与施工条件对塌方洞段处理方案进行对比研究,最终提出了技术可行、经济合理的处理方案,对穿越类似不良地质的隧洞施工具有参考意义。
The water supply engineering of Dongshan in Shanxi Province is located at loess hilly landform, the formation is alluvial district. The soil is composed by sand, gravel and silt, so this location has the problem of seepage and gushing. This will cause the roof-falling of tunnel face in construction of tunnel. According to the geological conditions and construction condition, the treatment scheme is compared. At last the treatment scheme of technical feasibility and economic rationality is proposed. Results of this paper provided reference significance for the tunnel passing through the adverse geology.
