Research on Project Management of Slab Track Construction Equipment;

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;

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.

Through centrifugal model test of pile-plank subgrade for ballastless truck,the settlement and pile-soil interaction of pile-plank subgrade are studied.

The pile-plank embankment is a kind of new-type of ballastless truck in high-speed railway.

Pile-plank embankment is a kind of new-type form of ballastless truck in high-speed railway, it is composed with the reinforced concrete plank at its upside and reinforced concrete piles, subgrade and subground at its downside, and plank directly connectes with the track structure, the piles fixedly link to plank and together with the subgrade compose a bearing load structure system.

This article briefly introduces some experiences on application of rail haulage and and trackless muck-loading technology during the construction of sipujian double-line tunnel on Shuohuang railway,which is state major construction project.
