In the basic structural type often used in cable-stayed bridges, for the beam-tower pier connection type for tower-beam fixed, beam-pier hinged (such as the French Porudongna Bridge, Shanghai Mao Hong Kong Bridge, etc.), tower-pier fixed, tower-beam hinged (or tower-pier fixed, beam-pier hinged, such as the Liaoning Changxingdao Bridge, etc.), or tower-pier fixed, tower-beam separation floating structure (such as the U.S. P-K Bridge, Shanghai Nanpu Bridge, etc.). When hanging orchid cantilever construction, in order to prevent the main beam instability caused by the asymmetric bending moment and horizontal force generated by the construction load on the pier support, must be taken temporary consolidation measures
