摘要

Increased demand on rail tracks owing to decreased intervals, heavier and faster trains and the wearing of old railway lines often requires improvement of the ground and sub-ballast beneath conventional ballasted rail tracks. The rail traffic should not be restrained; thus methods are welcome, which allow a soil compaction or replacement of the soil while tracks and sleepers remain in place. In the current paper methods are presented, which allow a deep improvement of poor and soft soil beneath the rail track and a complete exchange of the near-surface rail track structure including the base layers, ballast, sleepers and tracks.
