Two finite element models are established to calculate the additional longitudinal forces of the integrated system consisting of track,beams,abutments,piers and foundation,and the additional longitudinal forces of a big frame bridge with two slender piers are calculated.

The mode of additional longitudinal force of continuously welded rails on bridge with continuous beam is established.

With the track, bridge and its piers taken as an integrated system, the finite element model to analyze the additional longitudinal forces in continuously welded rails (CWR) on bridges was established.

The mutual additional longitudinal force transmission between continuously welded rails (CWR) and high-speed railway bridges is an important force for high-speed railway bridge.

Study on additional longitudinal forces of jointless track on curved rigid frame bridge;

Back analysis of vertical additional force on shaft lining based on monitoring information and its failure analysis

After the test, the data calculation showed that under the vertical additional force, the mine shaft lining connector has good vertical compressed deformation featu.

This reduction of the bearing center distance will lead to create additional radial pressures between teeth of meshing gears, thus make the gearing operate under the condition for both profile surfaces of the tooth to engage.
