摘要
将施工中存在初始缺陷的高桥墩视为两端铰支的压杆,采用瑞利—里兹法推导其稳定临界压力公式。利用公式进行计算,算例结果表明初始缺陷的存在会降低桥墩承载力。
For high bridge piers with initial defects in construction,this paper,regarding them as compression bars with hinged supporting on both sides,derives stable critical pressure formulae for piers by means of the Rayleigh-Ritz Method and calculate based on formulae.The calculation result shows that the existence of initial defects will reduce the bearing capacity of piers.
