用结构力学的弹性中心法结合两个弹性体接触的理论,给出仰拱与地基间的接触压力,在此基础上,以微弯曲梁为模式,给出了问题的垂直振动解,以此为计算仰拱垂直地震力。
Based on the theory of structural mechanics elastic center and the contact between two elastic bodies, the contact pressure between the inverted arch and the foundation is given. Based on this, the vertical vibration solution of the problem is given based on the mode of the microbending beam To calculate the vertical seismic force of the inverted arch.
