地铁暗挖施工中的不良地质超前注浆加固技术

Technology of advancing slip casting consolidation under bad geology in subsurface excavation of metro construction

通过在沈阳地铁二号线沈阳北站站下穿北站路暗挖段的施工实践,介绍超前注浆加固在不良地质处理上应用的成功经验,为类似的问题处理提供一个解决方法。

By the practice of subsurface excavation of Shenyang metro construction in line 2 from Shenyang Beizhan to Beizhan Road,the pa-per introduces the successful experiences about the technology of advancing slip casting consolidation under bad geology,and provides a prob-lem-solution approach for handling for similar problem.
