Laboratory experiment study on the ballast and ventilated railway embankment in permafrost regions;

Test and Study on Ballast Elasticity and Accumulated Deformation;

Effects of Ballast Thickness on Rail Track Structure;

Precisely survey for ballastless track in the passenger dedicated railway line;

A new method for dynamics modeling of ballastless track;

Influenced of train speed on dynamic characteristics of ballastless track subgrade;

Analysis of parameters effects on settlement of ballasted track;

Construction technologies and quality standards of ballasted track engineering for Passenger Dedicated Railway are introduced,and the construction process is outlined.

The application of ballastless slab track is the main tendency for assuring the high stability and smooth of the track.

Taking the rapid transit from Tianjin to Binhai New Area for example, this article gives a description of the preliminary design, construction organization and budget estimate making for the track-laying on viaducts, and makes a comparison with the actual field construction to explore the construction organization of slab track of the rail transit system and performs a cost analysis thereof.

Study on the new unballasted track technique of passenger dedicated line

Based on a general review of the present development of unballasted track for high speed railwag in China and abroad,the unballasted track for Qin-Shen passenger train is comparatively analyzed in general structure property,manufacturing and construction,track maintainance,etc.
