对曲线正矢偏差管理值设置的原理进行推导,建立静态保养标准与动态平稳性之间的关系,为曲线正矢偏差管理值的设置提供理论依据,提出提速线路曲线分类和正矢偏差管理标准,对保证曲线动态平稳具有重要指导意义。
The principle of setting the management value of curve positive deviation deviation is deduced, and the relationship between static maintenance standard and dynamic stationarity is established to provide theoretical basis for the setting of management value of curve positive deviation. The classification of acceleration line curve and the standard of positive deviation management are put forward. It has important guiding significance to keep the curve dynamic and stable.
