Low precision in closure and in appropriate track configuration of built bridges is a general problem in the construction of cantilever-concreting railway bridges.

The construction control technique of high pier slide form;

The application of non-bracket turnover form method in high pier construction;

Discussion on the cross section types of high piers of bridge and stability calculation;

The three-dimensional finite element model of a continuous rigid frame bridge with long span and tall pier is established and the stability coefficient of safety and modes are calculated through the application of the finite element analysis software.

It is shown that the tall pier remarkably differs from the lower pier in seismic demands when the higher v.

In this paper,the applicable calculational methods of displacement ductility capacity are summarized,and varied parametric models of tall pier are analyzed with Pushover analysis method and formula method.
