膨胀性泥岩对隧道明挖施工的影响评价与处置对策

The study of effects evaluated and countermeasures about the influence of expansive mudstone on open-cut method of tunnel

分析了膨胀性泥岩隧道强度和稳定性以及膨胀性泥岩明挖施工对隧道两侧内衬混凝土的影响,探讨了隧道两侧土体的支护设计与施工,并提出可行性对策,对以后的泥岩隧道支护与施工有重要意义。

Through the research on the strength of the expansion and stability of expansive mudstone and mudstone tunnel excavation construction on both sides of the tunnel lining concrete,to explore the soil on both sides of the tunnel support design and construction,and puts forward some feasible countermeasures.It has important significance on mudstone tunnel support and construction in the future.
