Abstract: E. Winkler assumption has been widely used to calculate the internal forces on the beams for the design of the oundation beams in port engineering.Many computational methods based on this kind of assumption are used, and some diagrams have been compiled.But, there exists a problem that the arrangement of the most disadvantageous position of loads has been used to find out the maximum bending moment values on each cross-section under the action of moving wheel loads, a large amount of calculations is still needed.For this purpose, this paper provides us a set of bending influence line diagrams of the uniform cross-section beams on elastic foundation under the action of the concentrated forces and couples, which makes calculation simple and convenient.These diagrams cannot be found in common diagrams, they are specially convenient for the dock floors calculation.
