THE INFLUENCE OF DIFFERENT ROADBED ENGINEERING CONSTRUCTION ON THE ROADBED CRACK OF QINGHAI-TIBET RAILWAY

Based on the experimental results of the temperature and deformation of reinforcement embankment and station roadbed in some tests of the Qinghai-Tibet railway, the authors analyze the characters of ground temperature and deformation in reinforcement embankment and station roadbed. The influence of different roadbed engineering construction on the roadbed crack due to embankment reinforcing and roadbed widening is then characterized.
