| 1. | Thrust block may bridge the space between the termination of the arch and the foundation rock at the same elevation . 推力墩可以跨在拱脚和同高程的基岩之间。 |
| 2. | Fem stress analysis of springing joint for cfst and rigid frame tied through arch bridge 下承式钢管混凝土刚架系杆拱桥拱脚有限元应力分析 |
| 3. | Design and construction of foundation ditch project of floor - type arch springing foundation of reticulated shell structure 网壳结构落地拱脚基础基坑工程设计与施工 |
| 4. | To solve horizontal thrust at arch feet and rheological change in soft soil is the first problem for arch bridge construction on soft soil ground 在软土地基上建造拱桥首先要解决拱脚处的水平推力以及软土地基的流变问题。 |
| 5. | To reducing the compressive stresses at the impost of arch , we optimized this part and obtained a good result so as to offer a scientific basis for design 针对拱脚压应力较大的情况,进行了局部加大的优化处理,取得了较好的效果,为工程设计提供了科学依据。 |
| 6. | The biggest difference from the usual down bearing arch structure lies in this points that the four tectonic cracks on its two down beans ca n ' t constrain the level forces 它与常规的下承式拱架支承结构的最大区别在于它的两道下弦杆设置了四道断缝,从而使下弦杆失去对拱脚水平力的约束作用。 |
| 7. | 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。 |
| 8. | On the basis of analyzing effect of prestressed tendon layout on internal force and thrust at springer , the principle of prestressed iendon layout for three - span prestressed concrete deck arch bridge is illustrated 摘要在分析预应力布置位置对三跨上承式拱桥内力和拱脚推力影响的基础上,阐明了该类桥型预应力筋的布置原则。 |
| 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。 |
| 10. | For example , no - supporting elements should be made of light material which attracts less seismic loads . 2 ) generally speaking , seismic combined maximum loads of aqueduct transverse direction is less than 100kn , which present joints near the arch - foot sections 2 )总的来看,各质点横槽向的地震总名义合外力不大,最大值不到100kn ,且发生在支座附近紧临拱脚的节点上。 |
