摘要
随着国家中东部地区经济的发展,交通运输也得到了前所未有的改善,国家交通建设的重点开始转移到西部地区,西部地区处于我国三级阶梯的高原山区,这就决定了山区交通建设的一个突出特点是长大下坡,这对于重型车辆来说非常不利,极易造成刹车系统的温度失效,酿成惨剧.本文从制动系统的温度效应模型开始研究,通过改变各个影响因素的大小,并进行实验验证,对避险车道的设置位置进行了分析,并对避险车道的长度进行了研究,得到了避险车道的设置位置和设置长度计算公式,为山区公路避险车道的设置提供了参考.
With the China＇s economic development in the eastern area, transportation has also been an rapidly improvement. The focus of national transportation construction begins to shift to the west area, which located in the mountain plateau of three ladders in China. Long-high downhill is a prominent feature of mountain transportation construction, that is very unfavorable for heavy vehicles. Particularly likely to cause temperature failure of the braking systems,and making serious tragedies.This paper, starting from the study of temperature effects model of the braking systems, it analyzed the location of the truck escape ramps. By changing the value of the factors, and verified through the experiment,gives a research to the length of the truck escape ramps, and it gets the setting-position and setting-length of the truck escape ramps, which provides a valuable reference to the setting of it.
