抚顺东露天矿西端帮土体及公路压密注浆加固施工技术

Construction Technology of Compaction Grouting Consolidation in the Soil and Road of an Open-pit Mine in Fushun

摘要:

抚顺市东岗道桥公路由于连接东、西露天矿的隧道施工及东露天矿西端帮剥离致使东露天矿西端帮土体滑移，路面出现裂隙、变形，迫使东侧公路停用。结合地质情况，采用压密注浆施工技术对东露天矿西端帮边坡土体、公路进行压密注浆加固处理。经测量数据检验，东露天矿西端帮边坡及公路沉降变形趋于稳定，达到预期效果，保证了东露天矿西端帮边坡稳定及公路的正常安全使用。

Abstract:

At a road of Fushun, soil slip was caused by a tunnel construction connecting the east and west open-pit mines and the west end slope striping of the east open-pit mine with cracks and deformation in the road. According to the geological conditions, compaction grouting construction technology was adopted for compaction grouting consolidation. By the measurement data test, the west end slope and the road settlement deformation trended to be stable, which ensured the stability of west end slope of the east open-pit mine and the normal safety of the road.
