摘　　要：综合考虑梁截面转动、相邻截面剪切变形和横向压力等影响推导出弯曲矩形截面深梁的新理论。作为算例,应用虚拟功的互等法具体求解了在均布载荷作用下两端简支深梁的弯曲问题,给出了这种情况的数值计算结果,与ANSYS有限元结果进行了对照,验证了该新理论的正确性。In consideration of the rotations, shearing deformation of adjacent cross section and the transverse pressure, a new theory of deep beams of the rectangular cross section is derived in the paper. As a numerical example, the bending of deep beam with two edges simply supported under the uniformly distributed load is solved by the use of fictitiously reciprocal method of work. The nu- merical values are compared with the results from ANSYS. The correctness of the new theory of deep beams of the rectangular cross section was verified.
