一、外荷载作用下柔性墩静力分析的初值解在外荷载作用下(见图1),距墩顶截面y处墩身截面的横向位移x_y、转角φ_y、弯矩M_y及剪力Q_y的初值解为: 式中x_0、φ_0、M_0及Q_0为墩顶截面(y=0)处的变位及内力;k为柔性墩的变形素数,其量纲为1/长度,按下式计算: First, the initial solution of the static analysis of the flexible piers under external loads Under lateral load (see Figure 1), the horizontal displacement x_y, the angle φ_y, the moment M_y and the shear force Q_y The initial solution is: where x_0, φ_0, M_0 and Q_0 are the displacements and internal forces at the top section of the pier (y = 0); k is the deformation prime number of the flexible pier with a dimension of 1 / length and is calculated as follows :
