考虑地震、波浪和海流作用的跨海桥梁结构研究进展

随着我国经济建设的快速发展,近几十年来大型的跨海桥梁工程结构不断涌现,服役期内跨海大桥可能同时承受风、波浪、海流、海冰、潮汐和地震等其中的几种联合作用,有关此方面的理论、数值和试验研究还比较缺乏.主要对近年来跨海桥梁结构在承受波浪、海流、地震单独或联合作用下的理论、数值、试验研究与进展进行了综述,并对桥梁结构考虑波浪、海流作用的水下振动台试验的发展进行了展望.

Research progress of sea-crossing bridge structure considering action of earthquake, wave and current

With the rapid development of economic construction in our country, large sea-crossing bridge engineering structures have emerged in recent decades. In service period, the sea-crossing bridge may also undergo the united excitation of the wind, wave, current and sea ice, tidal and earthquake, etc.. However, almost few theoretical, numerical and experimental studies on these aspects exist. Firstly, the theoretical, numerical and experimental research and progress of sea-crossing bridge structures under the separate or joint action of waves, currents, earthquake are summarized. Then, the development of the research of the bridge structure underwater shaking table test considering the wave and current action in the future is prospected.
