| 2. | Evaluation of the effect of collapse in top area of a double - arched tunnel on its the secondary lining 双连拱隧道洞顶坍方对二次衬砌稳定影响评价 |
| 3. | Legal problems existed in railway transport enterprise when turning secondary lines of business into independent companies and counter measurements 铁路企业辅业改制存在的法律问题与对策 |
| 4. | Invention of out - going secondary line switch , resulting in economy of inter - office trunks . first used at san francisco 发明外向第二级寻线机,提高了局间中继的收益,并首次在旧金山使用。 |
| 5. | Through tunnel model test , the action law of external water load on secondary lining with a grouting loop is obtained 根据隧道模型试验理论,通过室内模型试验得出了有注浆堵水圈的隧道衬砌结构外水荷载的作用规律。 |
| 6. | Optimized techniques for fabricating the secondary lining of a two - storey shallow subway station with single arch and one row of columns excavated by mining method 单拱单柱双层浅埋暗挖地铁车站二次衬砌优化施工技术 |
| 7. | However , where a secondary line is too small to be included in the indices , the xd adjustment is calculated using the dividends paid on the main line and the combined share weighting 但是,非主营业务的数值太小了可以忽略不计入指数,除权调整就用主要业务的支付红利和加权的股份比重计算。 |
| 8. | Pass through mechanical model calculate , discover the vault and arch foot part in the tunnel secondary lining thickness is weakness part , so at the design and construction must strengthen these part 通过力学模型计算,结构在拱脚与仰拱交接处以及拱顶部位为隧道二次衬砌混凝土结构的薄弱部位,设计和施工时应着重加强。 |
| 9. | At the part vault and arch foot in the tunnel secondary lining thickness , the standard difference and variance parameter is large than others , so insure the part thickness achieve design require by adjust construction craftwork 隧道二次衬砌厚度在拱顶和拱脚的部位的标准差和变异系数较大,在施工中应该考虑调整施工工艺,确保这两个部位的厚度。 |
