Toughness design-based support arrangement system of full-floating bridge
The invention relates to a full-floating bridge support arrangement system based on toughness design. A collapse prevention support is arranged on the lower edge of a main beam at a cable bent tower; during normal operation, the anti-collapse support does not make contact with the main beam, and no effect is generated; when the suspender close to the tower is broken, the main beam falls down and is in contact with the anti-collapse support; the anti-collapse support is separated from the bottom of the main beam, and a certain gap delta is reserved; delta is greater than a downwarping value a of the main beam during normal operation; delta is smaller than a downwarping value b (alt) of the main beam after the inhaul cable is broken; [delta] lt; b). Compared with the prior art, the anti-collapse support is arranged, so that the risk that the main beam collapses under the condition that the inhaul cable is broken is avoided. Supporting is provided after the inhaul cable is broken, and bridge collapse is avoided.
本发明涉及一种全漂浮桥梁基于韧性设计的支座布置体系，索塔处的主梁下缘设置有防坍塌支座；正常运营时，防坍塌支座与主梁不接触，不产生作用；当近塔处吊杆断裂时，主梁下落，与防坍塌支座接触；所述防坍塌支座与主梁底脱空，预留一定间隙Δ；所述Δ大于正常运营时主梁的下挠值a；所述Δ小于拉索断裂后主梁的下挠值b(a<Δ
