软破围岩中浅埋大跨人防工程锚固综合技术的研究
|
摘要
本文首先对该工程围岩稳定性进行科学评价 ,并确定围岩类别 ,以锚为主。施工中对开挖顺序进行调整 ,对锚索、锚杆注浆工艺进行改进 ,保证了施工安全和工程质量 ,取得良好的技术经济效果。
The requirement on safety of underground air defence chamber is very high,especially when the chamber is shallowly buried,of wide span and surrounded by poor rock.Of similar conditions is the Longshan underground store in Oingdao city which can be used as air defence shelter in war.To ensure a safe construction and provide a high quality chamber with long service life,technique of such as long cable anchor,short bolt,steel wire mesh,steel fibre shotcrete,steel arch frame has been successfully adopted for strengthening the wall rock.
