机场滑行道桥双孔箱涵结构地震力计算

摘要
机场内的构筑物有其一定的特殊性,国内外尚未见对机场工程地下结构抗震问题的研究。介绍了一种适用于软土浅埋地下结构的抗震设计计算方法,并将该方法应用于某机场下穿通道工程刚构结构的地震力计算。分析表明,机场飞行区内的刚构结构具有较好的抗震能力,刚构结构将成为机场地下通道工程有竞争力的解决方案。
Airport structures have certain professional particularity.Currently there is no seismic effect research on the underground structure of the domestic and international airport project.The calculation method of seismic force on the shallow-buried structure in the soft soil is introduced in detail in the article,which is firstly applied to calculate the rigid-frame in the airport project.The results show that the seismic capability of the rigid-frame structure in the airfield area of airport is very well.And the rigid-frame structure becomes recently a competitive solution for the airport underground project.
