ABSTRACT
Method (Zienkiewicz, O.C. 1972) and can be used for rather complex numerical models, the evidence being (Králik, J. & Šimonovič, M. 1993).
2 STRUCTURAL JOINT IN THE 49 E1 TRACK
The 49 E1 rails are connected every 25 m by means of different types of joints. This paper deals only with the rail joint type which is used in railway tracks in the Ostrava-Karviná Coal Colliery where the track superstructure has been suffering from undermining effects. This is a S joint-see the Figure 1 on the left. The rail joint is fixed to the rail by means of four bolts, Ø 24 mm. The surface of a rail joint should preferably match up with outer surfaces of the rail. The bolts are tightened up with a torque spanner up to 180-210 Nm.
