桥面板防倾覆模拟分析及预警系统设计

针对单柱支撑桥面板这一结构,进行变宽度、多跨度桥面板的偏载倾覆专题模拟计算,分别得到相应条件下的桥面板倾覆临界值,将临界值输入内置变送器、单片机和报警器组成的预警系统,从而可有效防止因偏载造成的桥面板倾覆事故的发生,为桥梁工程防灾减灾提供了一种方法和思路.

The Simulation Analysis and Early Warning System Design for Bridge Deck Capsized

For the structure that the bridge deck supported by single column, special simulation of load overturning basing on changing the width or span of bridge deck is calculated to get the overturning critical values, under the corresponding conditions, of the bridge deck. Putting the critical value in the early warning system, which contains built - in transmitter, Single Chip Micyoco and alarm, can effectively prevent the occurrence of the overturning accident causing by unbalance loading and provides a new method and idea for disaster prevention and mitigation in bridge engineering.
