钢-混组合梁桥面板-防撞护栏一体化钢模板设计分析

以嘉兴市市区快速路环线工程中某联钢-混组合梁桥施工时需要跨越某汽车4S店实例为背景,设计了桥面板-防撞护栏一体化钢模板,施工时先后作为桥面板和防撞护栏混凝土浇筑模板,可有效防止桥面坠物并保证施工安全。结合工程特点,对一体化钢模板进行了参数化设计,证实了该类型模板的适用性,得出了具有一定参考价值的结论。

Design and Study on Integrated Steel Formwork of Steel-concrete Composite Beam Bridge Deck - Anti-collision Guardrail

Affected by the construction environment and economic conditions, the monitoring of stayed cable safety of small-span and medium-span cable stayed bridges is generally completed only through a few sensing facilities arranged on some stayed cables. How to arrange a few sensing facilities at the proper position of the bridge stayed cables and obtain the closest data to the actual situation has become one of the key problems to be handled in the design of bridge safety monitoring, and the proper position can be determined only by the relevance of the stayed cable.
