Contact Loss Between Railway Track and Subgrade in Vertical Plane During Roadbed Research
|Published in:||Journal of Civil Engineering and Management, March 2003, n. 1, v. 9|
In the paper a new method of railway subgrade investigation is analysed. Contact loss between track and subgrade in vertical plane is considered. During the roadbed investigations the rail is jacked up using a plate called „VSS”. It is assumed that variable temperatures have influence on the rail which is laid on a curved roadbed. Elasticity of the railway roadbed is calculated. Finally formulas and dependences of various types of track structures are obtained.
