根据10余年来桥梁墩台制动力试验研究所取得的成果,说明简支梁桥在承受列车纵向水平力(制动力、牵引力)时具有极为显著的整体性,即全桥各墩、台、梁连同桥头引线形成共同受力体系以承担纵向水平力。而且桥上有载孔梁上纵向水平力向其它无载孔梁传播时,主要是通过钢轨(包括护轨)传
According to the results of more than 10 years’ experimental research on bridge piers and abutments, it shows that the simple supported girder bridge has a very significant integrity when it is subjected to longitudinal horizontal force (braking force and traction force) Together with the bridgehead leads form a common force system to assume longitudinal horizontal force. And the bridge on the load beam vertical longitudinal force to the other non-load hole beam propagation, mainly through the rail (including guardrail) transmission
