摘要
采用非线性计算方法，分析影响圬工桥墩弯矩增大系数各主要因素的性质，建立用于设计的弯矩增大系数实用计算公式，并通过回归分析，建立了有关系数的表达式。
Based on the non-linear analysis method, the moment magnification of concrete and masonry piers is calculated, and affecting behavior of every primary factors is analysed, A calculating formula of the moment magnification ratio for designing is established. By use of regressing analysis, expressions of some relative coefficients are proposed.
