新建公路连续长、陡下坡路段确定避险车道位置的方法

Method for determining the escaping lane of new highway for continuous long and steep downhill section

为合理确定避险车道位置提供定量化依据,降低避险车道设置的不确定性,通过理论分析和工程实例验证,并结合国内外相关研究成果,提出了车辆制动器实时温度计算方法,并依据计算结果给出了设置避险车道的原则,为新建公路确定避险车道位置提供了定量化的参考依据,可指导新建公路长、陡下坡路段避险车道的设计。

In order to quantitatively determine the position of escaping lane,according to the theoretical analysis and engineering examples of validation and combined with the relevant research achievements,the calculation method of the real time temperature of the brake is put forward.Based on the results presented the principle of escaping lane,which can guide the design of long and steep downhill escaping lane and provides a quantitative basis.
