ON RESISTANCE OF TIES TO MOVEMENT

Some 900 tests on displacement in the transverse direction to the centerline of the track laid on wooden ties and with ballast in normal state were conducted in Russia. The curve obtained between force and displacement shows continuous increase of force with displacement reaching a maximum of 946 klg. for the displacement of 5 cm. A second series of tests was conducted near a structure that supplied an anchor point permitting to apply pull on three ties simultaneously. In displacement of ballast up to .75 cm the resistance increases rapidly and continues to increase up to 2.75 cm displacement. At the end of movement equal to 5 cm the force reaches 486 klg. The resistance of the ballast in the shoulder decreases from 51 Klg. for 75 cm displacement to 18 Klg. at 5 cm. These experiments indicate that the ties have a tendency to wedge between the ballast and the base of both rail strings with results that a force of 2500-3000 klg. is required to move them either in or out.
