基于PIARC制动升温模型的避险车道选址方法研究

基于PIARC制动升温模型，结合国内外研究成果和工程实际，在道路工程长大下坡的避险车道选址中，对避险车道设置的必要性、位置、间距和数量进行研究。结果表明:避险车道应依据PIARC温升曲线，再结合地形条件、《公路避险车道设计细则》（征求意见稿）的相关建议确定位置、间距和数量。

Study on Escape Lane Location Based on PIARC Braking Temperature Rise Model

For the location of escape lane of long and steep downgrade sections in road engineering, based on PIARC braking temperature rise model and combined with domestic and foreign research achievements and engineering practice, the necessity of escape lane and spacing and quantity were studied. The results show that the escape lane shall determine its location, spacing and quantity according to PIARC temperature rise curve, together with the terrain conditions, and the suggestions in the exposure draft of Guidelines for Design of Highway Escape Lane.
