基于辐射波理论，推导了在自由面波条件下、底水粒子运动边界条件下、结构与水速连续条件下空心圆墩的液控方程。应用变分离法，得到了一种计算空心圆墩内区水流速度的方法。在此基础上，提出了空心圆墩内区水附加动水压力的分析方法。通过对希腊Rion-Antirion大桥的动水压力附加计算表明，动水压力的增加会导致弯矩和剪力的增大，且空心圆墩内部区域水的影响不可忽视。
Based on the radiation wave theory,a liquid control equation for hollow circular piers was deduced under the condition of free surface wave,the movement boundary condition of bottom water particles,and the continuity condition of structure and water velocities.By applying the variable separation method,a method of calculating the velocity of water in the inner area of a hollow circular pier was gained.Furthermore,an analytical method for added hydrodynamic pressure of water in the inner area of a hollow circular pier was proposed.A calculation of the added hydrodynamic pressure for Rion-Antirion bridge in Greece shows that the added hydrodynamic pressure will result in the increases of bent moment and shear force,and the effect of water in the inner area of a hollow circular pier can not be neglected.
