| 摘 要： | 汽车与缆索护栏碰撞是一个极为复杂的力学过程,影响其动力反应的因素很多。碰撞后的护栏系统如横梁、立柱、地基的变形情况以及碰撞车辆的变形、运动轨迹、倾覆等情况也极为复杂,而且有很大的随机性。根据缆索护栏的受力特点,对碰撞过程进行适当的假设,建立车辆与缆索护栏碰撞的简化计算模型,可为高速公路护栏的设计、施工提供借鉴。

| Abstract: | The collision between vehicle and cable barrier is a very complex mechanical process,many factors impact its dynamical response.The condition of the barrier system after collision is extremely complex,such as the deformation of beams,columns and foundation as well as the deformation,trajectory and overturning of the collision vehicle with a lot of randomness.According to the force characteristics of the cable barrier,based on appropriate assumption,a simplified calculation model of collision between vehicle and cable barrier is established.The result is benefit for the design and construction of fence of expressway. |
