摘要
由于张石高速公路紧急避险车道在实际中发挥的作用较小,为了对其改造,对张石高速避险车道工程进行调研与勘察,通过对其设置位置的合理性、避险车道几何特性、避险车床制动能力、避险车床制动挖验等进行分析评价,指出不安全因素,提出改进措施与建议,可供类似工程项目参考与借鉴。
The emergency lane on Zhangjiakou-Shijiazhuang Expressway plays an unimportant role in actuality.In order to change this situation,researches and surveys of these lanes are conducted,and the unsafe factors and improvement measures are pointed out by analyzing and evaluating the emergency lanes from aspects of setting rationality,geometric characteristics,lathe braking ability and dug test of braking bed slope,which can provide reference for similar projects.
