ROADBED POST-CONSTRUCTION SETTLEMENT PREDICTION FOR A TRANSITION SECTION OF JIN-QIN PASSENGER SPECIAL LINE

摘要

The high-speed railway roadbed post-construction settlement control standard is very strict, its prediction has become an important research subject of high-speed railway construction.Although the prediction methods are various, each has its own applicability.Based on the field data of roadbed settlement for a transition section of Jin-Qin Passenger Special Line, this paper uses exponential curve method, hyperbolic curve method and cyclotron curve method to predict the post-construction settlement, the purpose is to select the best method according to the comparison result.
