1976年7月28日发生的唐山地震,使7度至11度震区的铁路遭到不同程度的破坏。 震区铁路正线约1100延长公里,遭受震害的占48.3％;根据193卒桥梁的统计,受到损坏的占39.4％。地震时,地基大面积失效,路堤开裂、坍塌、沉陷,轨道弯曲变形,桥梁岸坡滑移,墩台倾斜断裂,梁体挤撞以至坠落。其他如通讯信号、站场设施、给排水系统以及工业民用建筑等也普遍遭受损坏。 运行中列车有7列出轨,部分车厢倾覆,铁路运输中断,震害十分严重。
The Tangshan earthquake on July 28, 1976, damaged the railway from 7 degrees to 11 degrees in the earthquake zone to varying degrees. Earthquake area railway line is about 1100 kilometers extended, suffered damage accounted for 48.3%; according to 193 pavement bridge statistics, damaged 39.4%. Earthquake, large-scale failure of the foundation, embankment cracking, collapse, subsidence, track bending deformation, bridge slope slip, abutment tilt fracture, girder impact and even crash. Others such as communication signals, station facilities, water supply and drainage systems, and industrial civil buildings are also commonly damaged. There are 7 derailment trains in operation, some of them are overturned, rail transport is disrupted, and the earthquake damage is very serious.
