摘要
对于高 45 .6 m、宽 14.2 m、长 2 1.9m的地下洞室的开挖 ,视洞室围岩稳定要求 ,在开挖施工中采用了固结灌浆、深锚杆超前加固处理增加闸室顶部岩体强度 ,利用箱型衬砌钢筋混凝土加固洞壁的施工技术 ,并实行了严密的施工方案。
During excavation of the 45 6 m (H)×14 2 m(W)×21 9 m (L)underground cavity such techniquesas consolidation grouting,strengthening by means of long anchor bolts before excavation and strengthening the wall with reinforced box lining have been applied in accordance with the stability requirements for surrounding rock The construction was undergone in strict manner
