| 高速鐵路超大斷面隧道CRD施工技術(shù)(50 卷) |
| 英文標(biāo)題 |
| Construction technology of CRD method used in super-large cross section tunnel on high speed railway |
| 摘要 |
| 哈大客運(yùn)專線筆架山隧道開挖斷面積為209 m2，是當(dāng)今國(guó)內(nèi)斷面最大的高速鐵路隧道，設(shè)計(jì)采用CRD法施工。介紹了該隧道采用CRD(交叉隔壁法)法的施工工藝，同時(shí)針對(duì)該工藝對(duì)需要爆破的石質(zhì)地層的不適應(yīng)性，優(yōu)化了原設(shè)計(jì)的CRD施工工藝。對(duì)今后高速鐵路特大斷面隧道設(shè)計(jì)施工具有指導(dǎo) |
