Anti-overturning Control Methods and Applications for Single-column Pier Bridge
The prevention and control of overturning of single-column pier bridge should comprehensively consider the need for im-provement in anti-overturning stability performance and the selection of optimal design schemes based on environmental constraints a-round the bridge.By analyzing the overturning failure mechanism and overturning verification method of single-column pier bridge,three anti-overturning prevention and control ideas for single-column pier bridge are proposed:changing the structural failure mode,improving stability performance,and setting redundant constraints.After comparison,increasing the center distance between failed and effective bearings to improve the stability performance of single-column pier bridge has wide applicability in practical engineering.Propose two design ideas:increasing the number of bearings in the transverse direction of the bridge at the position of single-column pier to increase the spacing between bearings,and increasing the spacing between bearings(transitional pier)at the position of the abut-ment.Based on the actual situation of the bridge,five design methods are proposed,comparing and analysing the applicability and econ-omy of different methods.
