| 鋼管混凝土拱架在地鐵隧道中的應(yīng)用研究(49 卷) |
| 英文標(biāo)題 |
| Study on application of concrete-filled steel tubular arch to support metro tunnel |
| 摘要 |
| 淺埋暗挖法施工的地鐵區(qū)間隧道初期支護(hù)體系常使用格柵拱架承擔(dān)圍巖荷載，然而這類鋼拱架鋼材用量大，制作工藝復(fù)雜。鋼管混凝土拱架是一種承載力高、安裝簡(jiǎn)易、經(jīng)濟(jì)性能良好的新型支護(hù)形式。用鋼管混凝土拱架替代格柵拱架不僅可以降低工程成本還能加快施工速度。以荷載—結(jié)構(gòu) |
