钢筋

Numerical method was used to analyze the change in strength of members with flexures and axial force after spalling of cover concrete and effect of transverse reinforcement on their strength and ductility.

本文首先采用数值计算方法分析了钢筋混凝土压弯构件保护层混凝土剥落后强度的变化以及箍筋约束作用对其强度和延性的影响。

The arch bending on the top of the original main arch ring corresponds to every arch rib and the bottom beam on its landscape orientation. As a result it becomes a down arc frame similar to slab-and-beam floor system. On the arch bending and bottom beam just established, standing pillar, main beam, horizontal rib beam and bridge front-panel would be built subsequently. Both ends of the main beam would then be put off the new hat beam made of reinforced concrete. Now, it becomes an upper slab-and-beam floor system. Two decks will be joined together on the middle of the bridge, which forms the ability of spanning and loading.

在原主拱圈拱肋相应位置处增设拱伏，横向增设底梁，形成一个下层弧形的类似肋梁楼盖的结构；在已浇筑好的拱伏与底梁上，继续现浇立柱、主梁和横向肋梁、桥面板，主梁的两端搁置在桥台处新增加的钢筋混凝土台帽梁上，形成一个上层肋梁楼盖结构，并且上下两层楼盖在桥梁跨中互为渗透结合成一个牢固的整体，共同完成了跨越和承载的能力。

In this design, we have the total construction layout, such as from basic to the main, from the column and beam to the floor, masonry; another breakdown of the process, such as the support beam template, the Bangzha steel, concrete pouring, Also joined the safety management, construction and other projects of civilization, so that our construction design more comprehensive, concrete, to facilitate construction.

在本设计中，我们有总的施工布置，如从基础到主体，从柱、梁到楼板、砌体；又有分项的工艺流程，如梁模板的支撑、钢筋的绑扎，混凝土的浇筑，还加入了安全管理、文明施工等项目，使我们的施工组织设计更加全面、具体、便于施工。
