Abstract Research purposes: The design standard of the station yard of high—speed yard is very different from that of conventional railway．The curves behind the turnouts should meet the requirement of high running speed of train to enhance the capacity of train reception and departure of the station yard．Based on the model of vehicle—line dynamic interaction，the study is done on the effect rules of the length of inserted section in curves behind the turnout and the length of transition curves on the vehicle—line dynamic response，and the discussion is made Oil the rational parameter values of curves behind the turnouts for providing the theoretical basis to the design parameter of the station yard of high—speed railway．
Research conclusions: According to the comfortable requirement，the matching relationship between radius of curves behind the tumouts and superelevation under the conditions of different train running speeds，and the values of transit curves radius under different radius of curves behind the turnouts are given out．The study on optimizing the length of inserted section in curves behind the turnout and length of transition curves shows the length of the folded line between curves behind the turnouts should avoid taking the value of the sum of the fix distance and peak value attenuation distance in the first cycle of vehicle vibration on folded line．To the curves with radius of 1 200 m，the folded line length of 30m is unsuitable．When the length of transition curves behind turnouts is more than 50 m，the comfortableness is not improved obviously．
