arch-rib construction

基本解释

In this paper, the genetic algorithm is introduced to search the optimized closure state in arch-rib construction, which can be taken as the initial state of backward analysis.
为此，尝试嵌入遗传算法来确定钢管拱肋施工合龙前的合理状态，以此作为倒退分析的起点。
Detailed introduction is also made on arch rib lifting construction, which perfects the non-support cable crane system and provides good references for arch bridge construction.
目前，我国大跨度钢筋混凝土拱桥采用的施工方法主要有体外支架法、缆索吊装法、悬臂拼装法、转体法和劲性骨架法。
The visual calculation system in the swing-bridge construction is an arch rib stability analyzing calculation software, which aims at the light swing-bridge in the construction process.
转体桥施工中稳定性可视化计算系统是针对轻型化转体桥在施工过程中，拱肋稳定性分析的计算软件。

拱肋施工
In combination with the construction experience of an interchange spanning an expressway, this thesis systematically expatiates on the below-crossing steel pipe construction technology, the main bridge arch rib construction, the arch column construction, construction monitoring and so on.
本篇论文结合一座跨高速公路的立交桥工程实践，系统地阐述了该桥在高速公路下穿钢管的施工技术、主桥拱肋施工技术、拱上立柱施工技术及施工监测等。
