铁路大提速下的弯道设计

t present, the Chinese railroad regardless of is the passenger transportation or the freight transportation, the supply and demand contradictory extremely is very prominent. Therefore, fire truck unloading fast and further uses the existing resources enhancement operating efficiency extremely has the necessity. Demonstrated according to the investigation that our country has further proposes the fast ability. Raises fast must guarantee the train the safe operation, and the railroad curve design guarantees one of train high speed and safe operation key issues. This article is precisely embarks from this point, analyzing and researching the relations between curve design and train safe operation related factors. And defers to our design proposal, to the train lowest permission speed, the highest permission speed and the corresponding reliability, as well as further raised the fast feasibility to carryon the discussion. It provides the theory basis for the Curve design under High-speed railroad. So it has the certain practical significance.
