摘要：

对于承受特重车辆荷载的港口铺面工程,其设计已不能按适用于普通车辆荷载作用的铺面设计规范进行控制设计。文中以国外某港口中承受特重车辆荷载的铺面工程实践为例,对此类铺面板采用有限元方法进行了空间弹性地基板受力分析,根据分析结果,对铺面板按钢筋混凝土构件进行抗弯强度、抗剪强度计算及限裂性验算,能够较直观地得出各种荷载情况下,铺面最不利位置及内力大小。

For pavement in ports taking extra heavy duty vehicles, the existing design code for pavement for normal duty vehicles is no longer appropriate for control design of heavy duty pavements for ports. Taking as an example the engineering practice in construction of pavement to take heavy duty vehicles in a foreign port, the pavement of this type was analyzed with the finite element method for loads on spatial elastic foundation slabs. Based on the results of the analysis, the bending and shear strength of the deck slab was calculated as a reinforced concrete structure and the cracking limitation of the deck slab was also verified, which can directly give out the worst position and the magnitude of the internal force of the deck slabs under different loading conditions.
