摘要
本文介绍了一种宏观合成纤维增强预制混凝土轨道板的设计过程。分析是使用名为ATENA的先进有限元软件完成的(Cervenka et al. 2013)。除了静荷载外,预制板还进行了动荷载和疲劳荷载的校核。该结构在早期,脱模,旋转,提升和运输方面都得到了验证。通过分析,确定了所需的纤维用量。设计完成后,AECOM准备了两个完整板的真实规模测试。在试验过程中,利用检波器对不同位置的位移进行了测量。该试验的有限元模型保留了实尺试验的所有细节。试验结果与有限元模型的计算结果在每个校核案例中都很接近。
Finite Element Analysis of a Precast Fibre Reinforced Concrete Track Slab
In this article a macro synthetic fibre reinforced precast concrete track slab’s design process will be presented. The analysis was done with using advanced finite element software called ATENA (Cervenka et al. 2013). Beside the static loads, the precast slab was also checked for dynamic and fatigue loads. The structure was verified for early ages, for de-moulding, rotating, lifting and for transport as well. With the analysis a necessary fibre dosage was determined. After the design AECOM prepared a real scale test for two full slabs. During the test the displacements were measured on different places with using geophones. Finite element model of the test was made with all the details of the real scale test. The results from the tests and from the finite element models were close to each other in every checked case.
