摘要
波形梁护栏是我国公路及城市道路上应用最广泛的护栏形式,其安装方便、外形美观等特点显著,但安装方便随之带来的就是连接件的易损、易缺失等问题,如果得不到及时的维修养护,则很可能会带来严重的事故后果。采用计算机仿真方法对各种连接件缺失情况下的护栏防撞性能进行分析研究,得到了连接件缺失对防撞性能影响的关系曲线,为公路养护部门提供重要参考依据。
W-beam barrier is the most widely used barrier on highways and city roads,its easy installation and beautiful appearance is remarkable,but vulnerable components,easily lost and other issues appeared with easy installation. Serious accident may happen if no repair and maintenance immediately. This article analyzed various connections lack for barrier crashworthiness influence through computer simulation,relation curve of connection lack to crashworthiness were obtained,which give an important reference to road maintenance departments.
