公路桥梁震害及减隔震设计

On earthquake diseases on roads and bridges and seismic mitigation and absorption design

对公路桥梁上部结构、支座、下部结构、基础的震害形式进行了分析,依据减隔震设计的原理及现状,介绍了减隔震设计的装置及要求,并探讨了一些增加桥梁抗震结构的其他方法,以提高公路的抗震害能力。

The paper analyzes the forms of the earthquake diseases at the upper structure, the support, the lower structures and the foundation of roads and bridges, introduces the equipment and requirements for the seismic mitigation and absorption according to the principle and current sta- tus of the seismic mitigation and absorption design, and explores other methods to enhance the bridge anti-seismic structures, so as to improve the anti-seismic capacity of roads.
