本文提出了汽车撞上刚性混凝土安全护栏时的峰值冲击载荷的计算公式。该方程是使用全尺寸碰撞试验进行了不同的研究机构，包括莫纳什大学。理论和试验结果的比较表明，该方程提供了合理的精度时，预测峰值冲击载荷的汽车撞到一个刚性的混凝土障碍物为不同的冲击速度和角度。特别是，这些方程可以为桥梁工程师提供一个有用的手段，确定现实的峰值冲击服务负载时，设计桥面护栏。
This paper presents equations for determining the peak impact load of a car crashing into a rigid concrete safety barrier. The equations were validated using full-scale crash tests carried out by different research institutions including Monash University. Comparisons between theory and test results indicate that the equations provide reasonable accuracy when predicting peak impact loads of a car crashing into a rigid concrete barrier for different impact speeds and angles. In particular, these equations can provide bridge engineers a useful means of determining realistic peak impact service loads when designing bridge deck barriers.
