摘　　要：东北某铁路扩能改造工程拟提速至160 km/h,既有路基基床病害较为严重,大范围需进行病害治理及基床加固处理。经过调查分析既有线的历史、现状和病害原因,初步探讨基床加固承载力标准,确定较为经济合理的基床加固方案。A railway in the Northeast, after capacity expansion and reformation engineering, could speed up to 160 km/h. There have relatively serious subgrade diseases on the existing line, hence large range of disease treatment and subgrade reinforcement was required. By the investigation of the existing line＇s past and current situation and the analysis of the diseases causes, preliminary study was made in relation to the standard of subgrade bearing capacity so as to have a subgrade bed reinforcement scheme economic and reasonable.
