| 摘 要： | 青藏铁路冻土路基的稳定性是多年冻土区列车安全运营的重要保证．影响路基稳定性的主要因素是路基地温场的变化、路基两侧地表水以及地下水（冻结层上水、冻结层间水）和地层含冰量大小，即冻土路基防护措施的强弱和水热影响程度．保证冻土路基稳定性的防治原则是减少太阳辐射和周围环境的水影响，易采用路基两侧排水、增加片（碎）石护坡（道）、...

| Abstract: | Stability of embankment in permafrost regions along the Qinghai-Tibet Railway is an important issue for safe operation of the railway.The main factors that affect the embankment stability are the change of ground temperature field within the embankment,surface water and ground water on both sides of the embankment(water in the upper and lower frozen layers and between the frozen layers) and ice contains in the stratum,together with the protective measures and the environmental hydrothermal effects.The prote... |
