基于地震波介质载体动态传导规律的桥梁结构分析

地震波介质载体在地震发生时传递着能量,承载着地震信息。桥梁作为道路工程的咽喉,在发生大地震后的救灾中起着极其重要的作用。通过对地震波介质载体动态演化特征及规律的实质性认识和桥梁震害现象分析,探求其特性;从而将地震灾害演绎落实到以介质载体为核心,以震害媒介传递为路径的物质量级演变基础上,构建有限元模型。研究地震波不同介质对桥梁内力的影响,探寻其动态传递规律。

Analysis of Bridge Structure Based onDynamic Transmission Discipline of Law of Seismic Wave Medium Carrier

Seismic wave medium carrier of energy, carrying the seismic information in the event of an earthquake, as the road engineering throat bridge, plays a very important role in earthquake relief, through the analysis of the damage phenomenon of substantive knowledge and Bridge characteristics and law of seismic wave medium carrier dynamic evolution, to explore its characteristics, the earthquake disaster deduction into to the medium as the core, transfer to damage evolution path of the material foundation for the medium scale, constructing the finite element model, effects of different media on the bridge seismic internal force, to explore the dynamic transfer rules.
