With the high and strong materials and the thin wall structure used widely, the stability problem of the beam bridges with high-piers and long-spans becomes more and more important.

Pipeline jam accidents appear frequently during pumping construction of concrete of high-pier and long-span bridge,which result in not only great economic loss,but also serious delay of project completion.

This paper aims at bridge with high pier and long span adopting single or double featheredge piers, the stability of bridge in the whole construction process is analyzed combined with research conclusion of bridge stability and.

At tresent,there is no seismic design code for long span and high pier continuing girder bridges,especially under severe earthquake.

Based on the achievement of previous researches, this paper studied the application of pushover analysis on seismic analysis of high-pier and long-span continuous rigid frame bridge.
