In this paper, a mechanics model was proposed which can calculate the longitudinal force and displacement of seamless crossover on continuous beam bridge.

Measures to increase maintenance quality of continuous welded rail;

In this paper, the influenoe of coalmining on earth surface deformation and that on stability of the continuous welded rails are discussed according to the random medium theory.

As the use of continuous welded rail(CWR)increases in track structure,the derailing disasters associated with track also increase in great numbers due to the high compressive thermal stress.

Objective:To analyze the curative effect of non-phaco,sutureless,small incision through sclera tunnel,cataract extraction plus IOL implantation.

Key points for stress dispersion and stress locking construction for ballasted jointless track;

Track locking technology for laying of jointless track;

The analysis of the force on the jointless track in cross-sectional switch area and the maintenance measures in initial operation stage;

Probe into the Safety in the Horizontal-to-vertical Construction of in Cross-section CWR(Continuously Welded Rails);

CWR Vibration Characteristic Analysis under Different Temperature Force;

Optimization Design of CWR on Steep Gradient Viaduct with Small Radius in Urban Mass Transit;

A study on laying of jointless line for urban elevated light rail transit;

Connecting with the concrete examples, this paper expounds the construction scheme for the railroad switch squaring in the platform on the jointless line, which is the effective path and method for the displacement of the railroad switches.
