主 题:railway roadbed tilting-train bearing capacity settlement
摘 要:The tilting-train is very attractive to the railroad users in the world due to the advantage of high speed in curved track using pre-existing infrastructure of ***-train has a unique allowable speed and mechanism especially in curved *** this work,when tilting-train is operated with the allowable speed,the behavior of roadbed is evaluated by examining its settlement and bearing ***,the stability of roadbed is estimated as the roadbed is in the condition of soft soil influenced by the weather effects and cyclic train *** results show that the roadbed settlement satisfies the allowable settlement when the elastic moduli of upper roadbed and in-situ soil are greater than 3800 and 4600 kN/m2 for rail joint and 2300 and 3300 kN/m2 for continuous welded rail(CWR).
