| 摘 要： | 针对中国高速公路中间带护栏高度不足的问题，对高速公路中间带波形梁护栏的高度进行研究。采用能量守恒方法，在构建波形梁护栏和车辆计算模型的基础上，建立高速公路中间带护栏高度计算模型；并采用调查分析的方法，对交通事故、交通组成以及相关车型的设计参数进行分析，确定了护栏高度计算模型中的有关参数。研究结果表明，适合中国高速公路中间带波形梁护栏的高度宜为87．6cm，可有效地防止大型车跃出和小型车钻撞护栏等恶性交通事故的发生。

| Abstract: | The height of guard-rail in expressway median is very important for driving safety, it is necessary to study the corrugated-beam guard-rail height of expressway median. Based on the law of energy conservation and the idealized models of beam guard-rail and vehicle, a new model is put forward to calculate the height of guard-rail. Some parameters in the model are ascertained on the base of investigation about traffic accident, traffic composition, design coefficients of vehicles. The calculated results show that the reasonable height of the guard-rail should be 87.6 cm. This height can prevent the large size vehicles slopping over the guard-rail, and avoid the little cars going through the guard-rail. 2 tabs, 4 figs, 10 refs. |
