wearing surface on orthotropic steel bridge deck is a complicated yet still not well solved technical problem.
正交异性钢桥面铺装技术一直是困扰道路工程界与学术界的难题之一,至今尚未得到妥善解决。
especially under the effect of vehicles moving load, the fatigue reliability of the orthotropic steel bridge deck needs to been further studied.
特别是在车辆移动荷载作用下,这种复杂结构的疲劳可靠性有待于进一步研究。
finally, using the orthotropic steel bridge deck model, the difference influence of the single-wheel and double-wheel was studied and the least favorable positions was found.
第三,利用正交异性板模型研究水平和竖直荷载综合作用下正交异性钢桥面板铺装层的受力规律发现:铺装层各项力学指标对水平荷载的敏感性有较大差别;
the important parameters that influence the mechanical property of the paving layer on an orthotropic steel bridge deck are the paving layer thickness and modulus of the asphalt concrete surfacing.
影响正交异性钢桥面铺装层力学性能的重要参数有铺装层的厚度和沥青混凝土铺装层的模量。
