Background technology
Currently, only post Cast-in-Situ Continuous Beam structure type is used the curve bridge such as China's city intersection, high speed ring road more, should
Planting the substructure form of bridge has the advantages that reduction occupation of land, the increase visual field and bridge are attractive in appearance.But current China load-carrying vehicle
Generally existing overloading, individual vehicle overload even up to 200%~300%, causes this kind of bridge of structure type using
During there are a lot of capsizing cases.
The bending resistance for focusing on bridge of current Bridge Design person's concern, shear resistant capacity aspect are accidental for bias
Overload effect concern is not enough.Recent year Single column pier Continuous Box Girder Bridge capsizing case frequently occurs, and gradually causes related personnel
Self-examination.To find out its cause, most accident bridge pier column direction across bridge are using single fulcrum support, under overloaded vehicle uneven loading action, knot
The horizontal anti-overturning of structure is poor, and especially the bridge floor of only post ring road box girder bridge is narrow, conducts oneself with dignity small, and vehicular load is in Load Combination
In shared ratio it is great.Simultaneously as existing the standard of highway bridge is for regulation of the transverse overturning stability without correlation, place
The bridge lateral Stability Numerical Analysis under eccentric accidentally overload effect can often be ignored again when space state, design so that
Structure under accidental action is using bringing hidden danger.
It is more complicated Mechanics Phenomenon that structure is toppled, and belongs to the category of bearing nonlinear analysis.Before structure is toppled, must
Bearing so can be first produced to bias or even come to nothing phenomenon.After seat empty, the bearing for coming to nothing loses the supporting role to structure, only
It is left remaining bearing and constraint is produced to structure, this inevitably results in the redistribution of end reaction, necessarily occurs during this
Such as bearing vertical pressure causes support damage more than susceptor design intensity, and the deformation of bearing corner is excessive caused during toppling
Girder slippage phenomenon, therefore structure topples with whether seat supports effect is failed and be closely related.
