摘　　要： 求解钢筋混凝土多跨连续深梁的内力时 ,用有限元法可获得精度高的计算结果 .为方便手算 ,本文中采用五弯矩方程计算其内力 .方程中考虑了深梁轴线与刚性支座间的弹性压缩和梁的剪切变形的影响 ,文中还给出了计算边支座和中间支座不同弹性压缩变形的经验公式 . The internal force of the multi_span continuous reinforced concrete deep beam can be calcula_ ted with prevision by the finite element method. This paper presents a simple but effective method for calculating the internal force of continuous deep beam by using the five_moment equation. The effect of the elastic compression deformation between the axis of deep beam and the rigid support on the shear deformation of the deep beam was considered in the equation. The experience formula for determining different elastic compression deformations of the edge support and the intermediate support was given. The hand calculating method can fully meet the needs of engineering design.
